Samsung RB34C600EWW Review: What Three Sources Actually Found
Samsung’s 344-litre Series 6 is one of the most heavily rated frost-free fridge freezers in the UK, and almost none of that rating is testing. One consumer body has put it through a lab and keeps most of the result behind a paywall. One magazine measured the previous generation properly. Everything else is owners. We have separated the three, and printed the figures the retailers cannot agree on.
Where the reviews line up
Three sources, three completely different kinds of evidence. Which? has had this exact model in its lab and publishes its energy cost but not its scores. Tech Advisor measured pull-down times and noise on the previous-generation RB7300T, which is the same cabinet and the same 344 litres. And AO.com carries 667 buyer ratings across two colours of the identical machine. They do not contradict each other once.
Three things are agreed everywhere. It is quiet — 35 dB is the published figure at every retailer we checked, and the one source that listened to it in a room called it imperceptible in normal use. It holds temperature evenly: Tech Advisor found no variation between top and bottom shelves, which is what All Around Cooling is sold to do. And the usable space is the real selling point — SpaceMax thin-wall insulation is why a cabinet 595 mm wide and 1,853 mm tall holds 344 litres rather than the 300 or so a Bosch of the same footprint manages.
Two honest caveats. The energy rating is E, and E on a fridge freezer is mid-table, not good. At 254 kWh a year and the 26.32p unit rate in the cap from 1 October 2026, that is about £66.85 a year to run — though Which?, using its own assumptions, publishes £89.08. Both numbers are on this page because we are not going to pick one silently. And the shelves do not adjust: the one reviewer who actually lived with the cabinet found the fridge shelving fixed and the humidity setting fixed with it.
The buying decision is mostly about the split and the price. Retailers cannot agree whether this is a 70/30 or a 60/40 machine — the litres are the same either way, 230 in the fridge and 114 in the freezer, so read the litres and ignore the ratio. On price it swings by £220 between shops on the same day, which is the single biggest thing you control.
The three reviews this summary is built from
- Which?Lab test of this exact model, first reviewed Apr 2024, last checked Mar 2026. Energy cost public; every score paywalled.
- Tech AdvisorThe only published measurements we can read in full — but of the previous-generation RB7300T, not this one.
- AO.com4.8/5 from 331 ratings on the silver and 4.8/5 from 336 on the black, checked 18 Sep 2026.
Before the review: which machine is this, exactly?
The RB34C600EWW is the white one. Samsung sells the identical cabinet as the RB34C600ESA (silver), RB34C600EBN (black) and RB34C600DSA (graphite, with the SmartThings AI Energy trim). Samsung’s own site files all of them under the range name RB7300T, and calls the range “4 Series” on one page and “Series 6” on another. Retailers follow suit inconsistently — AO’s own URL for the black says “series-4” while the page title says “Series 6”. If a listing quotes you different litres for one of these codes, check the litres, not the badge.
Specification at a glance
Where sources disagree — and on this machine they disagree more than they should for a current product — both figures are shown with the name of whoever published each.
| Spec | Figure | Confidence |
|---|---|---|
| Energy rating | E | Agreed by Samsung UK, Which?, AO, Marks Electrical, Appliances Direct and Crampton & Moore |
| Annual energy use | 254 kWh | AO and Marks Electrical. Tech Advisor measured the previous generation at 256 kWh |
| Running cost | £66.85 a year at 26.32p/kWh · Which? publishes £89.08 | Our figure is 254 kWh at the Ofgem direct-debit cap rate for 1 Oct–31 Dec 2026. Which? uses its own assumptions and does not show them |
| Total net capacity | 344 litres | Samsung UK, Which?, AO, Appliances Direct. Marks Electrical lists 390 litres — see the disagreement note below |
| Fridge · freezer litres | 230 L fridge · 114 L freezer | Agreed by Which?, AO, Appliances Direct and Tech Advisor. This is the figure to trust |
| Split | 70/30 per Samsung UK, AO’s silver page, Marks and Appliances Direct · 60/40 per AO’s black page and Crampton & Moore | 230:114 is 67:33. The litres are identical either way |

Which?
Which? is the only organisation we can find that has put this cabinet on a test rig. It tests chilling power, freezing power, temperature stability and quietness, and it has done so on the black RB34C600EBN, which is the same machine as the white EWW in a different skin. The problem for anyone reading without a subscription is that the scores are precisely what is hidden: the category headings are visible, the star ratings under them are blurred, and the Best Buy or Don’t Buy verdict is behind the sign-up wall.
What is public is still worth having. Which? puts the annual energy cost at £89.08, confirms the E rating, lists 230 litres of fridge and 114 of freezer, gives the climate class as 10 to 43°C and the dimensions as 186 × 61 × 67 cm. Its energy cost is £22 a year above the figure you get by multiplying the published 254 kWh by the Ofgem cap rate, and Which? does not show the unit price it used — so treat the gap as a difference of assumption rather than a contradiction. The context Which? gives for free is useful too: across the fridge freezers it has tested, the lowest overall score is 39%, the average 62% and the highest 80%. This model’s own number sits somewhere in that range and we cannot tell you where.

This is the only hands-on test of the platform whose numbers are not paywalled, and we are labelling it carefully: Greenwood tested the RB34T602ESA, the model this one replaced. It is the same RB7300T range, the same 1,853 mm cabinet, the same 344 litres split 230 and 114, and the same 35 dB. What changed for the C-generation is the electronics — Wi-Fi, SmartThings and the AI Energy mode. The cooling hardware did not.
His measurements are the most useful figures on this page because nobody else publishes any. Loaded and started from room temperature, the fridge fell from 19°C to 5°C in one hour at a 23°C ambient, and the freezer reached −19°C in under two hours. More importantly, temperatures stayed consistent across every zone of the cabinet — no warm top shelf, no cold spot at the back — which is the claim All Around Cooling exists to make and the one most worth verifying. On noise he is blunt: 35 dB, and imperceptible in normal use. On energy he quotes 256 kWh and roughly £37 a year, which tells you more about August 2021 electricity prices than about the fridge.
His criticisms are the ones that survive into this generation, because they are physical. The fridge shelves do not adjust and the humidity setting is fixed, so you arrange your food around the cabinet rather than the other way round. And the power cable comes out of the top rather than the back, which matters if you are sliding it into a tight housing unit. He still rates it — “a modest gem” that does the basics without clutter — and praises the freezer drawers as genuinely sturdy.

Two rating blocks on the same machine in different colours, both landing on 4.8 out of 5, one from 331 people and one from 336. Quote the number with the score or it means nothing — 4.8 from 667 owners is a real signal in a way that 4.8 from nine would not be. These are buyers rather than testers, and they are rating a fridge freezer, which is a product category where most people have nothing to report and say so warmly. Treat it as evidence that the machine arrives working and keeps working, not as evidence about chilling performance.
AO is also the most complete spec source we found, and it is where two of the disagreements on this page surface. Its silver listing gives 254 kWh, 344 litres split 230 and 114, 70/30, 35 dB and 185.3 × 59.5 × 65.8 cm; its black listing for the identical cabinet says 60/40 and adds the noise class as B. On warranty AO is the clearest of anyone: two years as standard, extending to five if you register with Samsung within 90 days of purchase. That 90-day window is the single most expensive thing on this page to forget.
The practical costs are worth reading before you order. AO lists connection at £15, disconnection at £10, and door reversal at £40 — so if the hinge is on the wrong side for your kitchen, budget for it rather than assuming a reversible door is a five-minute job. Removal and recycling of the old machine and unpacking are free to members. A specialist site, Review Electricals, scores the same cabinet 9.0 out of 10 and cites “4.8 out of 5 from over 250 reviews”, which is consistent with AO’s blocks and is almost certainly drawn from them.

What holds up
- 344 litres out of a 595 mm cabinet — SpaceMax thin walls genuinely buy you space a rival of the same footprint does not have.
- Even temperatures top to bottom, measured rather than claimed.
- Fast pull-down: fridge to 5°C in an hour, freezer to −19°C in under two.
- 35 dB, noise class B — quiet enough for an open-plan kitchen.
- Frost free throughout, so no defrosting the freezer ever.
- Five-year warranty if you register inside 90 days, which is better than most at this money.
- 4.8/5 from 667 AO buyers across two colours.
What people complain about
- E energy rating. Mid-table, and about £67 a year to run at the October 2026 cap.
- Fridge shelves do not adjust, and the humidity setting is fixed.
- Power cable exits the top, not the back — awkward in a tight housing.
- 1,853 mm tall, so the top shelf is a stretch for shorter households.
- No water dispenser or ice maker at this price point.
- Reversing the door is a £40 job at AO, not a DIY afternoon.
- Retailers publish the split, and in one case the total litres, inconsistently.
Who it actually suits
Buy it if you have a standard 60 cm gap and a ceiling that will take a 1,853 mm cabinet, you want the largest usable fridge you can get in that footprint, and quiet running matters more to you than a top energy grade. For a family of three or four doing a weekly shop, 230 litres of fridge is the number that makes this worth the money, and the freezer at 114 litres is enough for a household that shops rather than batch-cooks.
Look elsewhere if your priority is running cost — an A or B rated cabinet of similar size will pay back the difference over a ten-year life — or if you need adjustable shelving for tall bottles and awkward loads, or if you are putting it in an unheated outbuilding without first checking the manual against the 10 to 43°C climate class. If you freeze in bulk, find a machine that publishes its kg/24h freezing capacity, because this one does not.
What we could not check
- The videos on this page were confirmed by search listing, not by opening them. youtube.com would not load for us — every attempt returned a 429 or a policy block — so each video ID and title was verified by appearing in two differently-worded search results instead. We could not read the channel name from those listings, and we could not confirm for ourselves that the videos are still public. Check before you rely on them.
- Which?’s actual scores. Chilling power, freezing power, temperature stability and quietness are all tested and all paywalled, as is the Best Buy or Don’t Buy verdict. Nothing on this page should be read as Which? endorsement, because we cannot see it.
- Freezing capacity in kg per 24 hours. Not published by Samsung, Which?, AO, Marks Electrical, Appliances Direct or Crampton & Moore. The 4-star rating is confirmed; the throughput figure is simply absent.
- Door swing arc and installation clearances. No source publishes the width the door needs to open, the hinge-side clearance, or the ventilation gap Samsung requires at the back and top. Those are in the installation manual and you should read it before measuring your alcove.
- Manufacturer RRP. Samsung UK’s own pages for this code do not show a price. The £639 and £679 “was” prices quoted by Appliances Direct and Crampton & Moore are retailer reference prices, not a manufacturer figure.
- Which?’s energy-cost assumptions. Its £89.08 is £22 above the £66.85 you get from 254 kWh at the capped rate, and it does not publish the unit price or usage profile behind it.
- Marks Electrical’s 390-litre figure. Its page for the silver lists 390 litres total and 276 in the fridge, against 344 and 230 everywhere else including Samsung. Those are the numbers for the taller RB38 cabinet, so we have used Samsung’s own 344.
- Long-term reliability. The C-generation has been on sale since 2023 and 667 ratings mostly reflect the first year of ownership. Nobody has published anything on how these are at five or ten years.
- Noise in a real kitchen. 35 dB is a laboratory figure and one reviewer’s impression. Which? scores quietness separately and we cannot see the score.
- No installer, forum or community source exists. We searched Reddit, the Samsung EU community and UK appliance forums and found no thread on this model. Two of our three sources are therefore editorial and one is buyer ratings, which is a thinner spread than we would like.
Sources and prices last checked 18 September 2026. The £66.85 running cost uses Ofgem’s 26.32p per kWh direct-debit cap rate for 1 October to 31 December 2026. Prices on this machine moved £220 between shops on the day we checked — check the listing in front of you before ordering.
