Samsung is the brand where the error code on the display depends on how old the machine is. The same drain failure reads 5E on an earlier washer and 5C on a later one; a door fault is dE then dC; a dryer overheat is hE then HC. That single quirk is why Samsung owners in Montreal find contradictory advice online for what is actually one fault.
Number One Appliance Repair is an independent local company providing appliance repair services in all Montreal areas. We repair Samsung refrigerators, washers, dryers, dishwashers, ranges and wall ovens in Montreal, Laval, the West Island, the South Shore, the North Shore, NDG, the Plateau, Saint-Laurent, Westmount, Verdun, LaSalle, Ahuntsic, Saint-Léonard and Hochelaga. Diagnostic is $149.95 flat, credited in full to the repair.

What do Samsung refrigerator codes like 21E, 22C, 40C and 88 88 mean?
Samsung refrigerators report cooling faults by naming the exact fan that stopped. 21E is a freezer-fan error, 22E or 22C is the fresh-food fan, and 40E or 40C is the ice-room fan — usually a blade frozen into its shroud rather than a dead motor. 33E points at the ice-pipe heater, and 5E at the fridge defrost sensor (we stock the DA32-00006W). PC ER and PC CH mean the boards have lost communication, most often through a chafed wire in the door-hinge harness. Two codes are not faults at all: OF OF is Cooling Off or demo mode, and 88 88 follows a power interruption during boot-up. On Twin Cooling Plus cabinets each compartment has its own evaporator, so one side can fail alone.
Why is my Samsung washer showing 5C, 4C or UE?
5C — 5E on earlier machines — is the Samsung code we see most: the washer will not drain. Before condemning the pump we pull the debris filter behind the lower access panel, then check the drain hose for a kink at the standpipe. A genuinely dead pump gets the DC31-00054A. 4C is a fill fault: taps part-closed, a kinked inlet hose, or clogged inlet screens. 4C2 means the hot and cold hoses are on the wrong taps, which we find constantly after a move. UE, Ub and U6 are unbalanced loads; Ur means the machine is still rebalancing. LC and 1C are leak-sensor trips, OC is overflow, 3C is a motor fault, and SUd is just too much detergent.
What does C80, C90 or HC mean on a Samsung dryer?
Samsung dryers grade their own vents. Clg, C80 and C90 are not part failures — they report duct restriction, C80 around 80 percent blocked, C90 over 90. HC (hE on earlier models) means the machine actually overheated, and tS, tO, tC and tE are thermistor readings out of range, again usually vent-driven. In Montreal the duct is often the real problem: condo laundry closets run several metres of flexible transition hose, and side-wall vents in Verdun and Rosemont ice over their flappers in January. We service electric dryers in Quebec. bE and 6E are stuck control buttons, AC and AE a loose harness between boards, and FC or FE an incoming-power frequency fault.
Why does my Samsung dishwasher show LC or 4C?
LC is the Samsung dishwasher code that frightens people: the base-pan leak sensor has tripped, and the machine will keep draining until it is cleared. Sometimes it is a real leak at the sump or the wash manifold; sometimes it is condensation on a very sensitive float. Either way we find the source before resetting anything, because a Samsung that keeps re-tripping LC over hardwood in Westmount or the Plateau is a flooring claim waiting to happen. 4C is a supply fault — often a flood-safe hose that has latched shut rather than a bad valve. 1E or IE means water is not passing the filter, 3C is the circulation pump, HC the heater, and 3E means the inlet water arrives too hot.
What causes C0, F0 and d0 errors on Samsung cooktops and ranges?
Samsung ranges and cooktops fault on their touch panels more than on their elements. C0, C1, C2 and C3 are sensor or stuck-button errors — a boil-over or a wet cloth left on the glass will do it — and d0 is the same story on one jammed key. F0, F1 and F2 are communication errors between the panel and the main board, usually a connector rather than a board. On induction models an underlined u is pan detection: the cookware is the wrong size or not induction-compatible. C to P is not a fault; it means a surface element is still on, so Self Clean will not start. We service electric and induction Samsung ranges in Quebec, not gas.
What is the -dC- partition error on a Samsung wall oven?
Samsung's split-cavity ovens carry a code no other brand uses: -dE- or -dC- means the Dual-Cook partition is missing or seated incorrectly, and the oven will not run the split program until it is back in its rails. tESt means demo mode is active and the oven will never heat — we see this on units that spent time on a showroom floor. C-2x is an overheat condition from a blocked or partially blocked vent; the numeric suffix varies by model. C-F0 is a communication fault between the range electronics, usually a loose connector. door means the plunger switch is not registering a closed door. A rattle from the back wall is usually a convection fan blade, not the motor.

Parts, platforms and what your model number tells us
Two things about Samsung make the model tag worth photographing. First, the fault-code convention changed: the same failure reads with an E suffix on earlier machines and a C suffix on later ones — 5E/5C, 4E/4C, dE/dC, LE/LC, hE/HC, bE/6E. A parts list written for one convention will not match a manual written for the other. Second, Samsung part numbers carry a division prefix — DA for refrigeration, DC for laundry, DD for dishwashers, DG for cooking — and parts catalogues are keyed to the complete model number, including the suffix printed after the slash. Photograph the whole tag rather than the first block of characters, because a part listed for one version of a model does not always fit another.
Québec's Bill 29 and your right to repair
Quebec's Bill 29, assented 5 October 2023, amended the Consumer Protection Act: planned obsolescence is prohibited, replacement parts must be installable with commonly available tools and without causing irreversible damage to the appliance, and the information needed to maintain or repair a good must be available in French. Since 5 October 2025, a manufacturer such as Samsung — or the merchant that sold the unit — must tell the consumer in writing, within 10 days of a repair request, the time within which it proposes to carry out the repair. Published legal commentary on the amendments notes that where the consumer does not accept that proposed timeline, the good may be repaired by a third party at the merchant's or the manufacturer's expense, provided the cost is reasonable. This is a plain-language summary of the statute and not legal advice — and as an independent repair company we have an obvious commercial interest in it. For how the law applies to your own appliance, contact the Office de la protection du consommateur.
Samsung repair in Montréal homes
Here is the Samsung-specific Montreal problem: power events. Samsung is one of the few brands in our fault-code reference that publishes dedicated codes for what happens after the power misbehaves. A fridge can come back from an outage showing 88 88, a communication or boot fault logged when power was disrupted during start-up, or sit in OF OF with cooling switched off. A dryer can report FC or FE when the incoming power frequency is out of range. The related trap is demo mode: a unit that spent time on a showroom floor can arrive with OF OF or tESt still enabled and never cool or heat. None of those are broken parts.
What Montréal customers say about their Samsung repairs
Called for my Samsung Fridge, French door problem. Great and speedy service. Technician (Bob) was very experienced and new exactly what he was doing. He replaced the broken part in less that 15 minutes. Great value for the money spent.
Frequently asked questions
Are you a Samsung authorized service centre?
No. Number One Appliance Repair is an independent company with no affiliation to Samsung. Our technicians are licensed and the business carries $2 million in liability insurance; Robert G., our master technician, started in the trade in 1986. We install OEM Samsung parts sourced through Canadian distributors and back every repair with a 90-day parts-and-labour warranty.
My Samsung code ends in E but the manual says C — which one is right?
Both. Samsung changed how it displays faults, so one failure appears with an E suffix on earlier machines and a C suffix on later ones: 5E and 5C are the same drain error, 4E and 4C the same fill error, dE and dC the same door error, hE and HC the same dryer overheat. Read the code off your own display and give us the full model number.
My Samsung fridge shows 88 88 after a power outage. Is it broken?
Not necessarily. 88 88 is a communication or boot fault logged when power was disrupted during start-up, common after a Hydro-Quebec interruption. A reset often clears it. If it returns, or if you also see PC ER or PC CH, the boards are genuinely failing to talk to each other, frequently through a chafed harness in the door hinge. Call (514) 416-1144.
Why does my Samsung ice maker keep freezing into a solid block?
Frost in the ice room is the most common Samsung refrigerator complaint we handle. The compartment shares air with the fresh-food cabinet, so a weak door seal, a failed ice-room fan (40E or 40C) or a dead ice-pipe heater (33E) lets the bucket freeze solid. We fit the redesigned OEM direct-contact heater clip rather than just thawing it out and leaving.
My Samsung dryer shows C80 or C90 — do I need a new dryer?
No. C80 and C90 are vent-blockage readings, not part failures: C80 means the exhaust duct is roughly 80 percent blocked, C90 over 90 percent. Clg is the same warning. Clear the lint screen, then have the full duct run cleaned — in Montreal condo laundry closets the flexible transition hose behind the machine is usually the choke point. If HC persists afterward, the thermistor or element is next.
Do you repair Samsung gas ranges in Montreal?
No. Our Quebec scope is electric appliances: electric and induction cooktops, electric ranges and electric wall ovens. Samsung sells all of those here and we service them in full, including the touch-panel codes C0 through C3, F0, F1, F2 and the split-cavity -dC- partition error. For a gas range or gas cooktop you need a contractor licensed for gas work in Quebec. We will say so when you call.
What does the $149.95 diagnostic include for a Samsung appliance?
A technician comes to your address in Montreal, Laval, the West Island, the South Shore or the North Shore, reads the stored fault codes, tests the suspect components and gives you a written repair estimate before any work starts. If you approve the repair, the full $149.95 is credited toward it. Repairs carry a 90-day parts-and-labour warranty. Hours are 6:30 AM to 9:30 PM, seven days.
