Samsung Dishwasher Repair in Toronto — Not draining / standing water

• 5E/5C is the drain fault that defines a Samsung not-draining call — Samsung Canada lists it as the drain error, 'difficulty in draining water,' so the tub stays full and the code latches. The documented trigger logic (from Samsung's DMT/DMR-series service manual, which carries over to the diagnostic family) is that the controller flags the fault when the OFF status of the low-level switch is not detected within about 3 minutes during the drain step. On DW80 platforms the most-replaced part behind a 5E is the drain pump, currently DD31-00005A (this is the CURRENT OEM number; the older DD81-01527A is superseded into it, and both cross to 1550731 / AP4342621 / DW0005A / PS4222308). It fits DW80F600, DW80J3020, DW80K5050 and DW80R5060/5061. We clear the filter/sump and confirm the pump motor has continuity before condemning it — 5E is never a reset-only fix once the impeller or windings have failed.
• Before any pump goes in, we rule out the case-break/overflow water-level sensor: on the DW80 platform that part is DD82-01373A (it supersedes DD82-01111A / DD82-01111B / DD81-02138A; x-ref AP6240655), and it fits DW80J3020US, DW80K5050UG/US, DW80R5060US and DW80R5061US. When the overflow/level sensor reads water level wrong — often after hard-water scale builds on it — the board can shut the cycle down even though the pump and hose are fine. Samsung's published DW80 guidance for the drain error is generic (inspect and clean the drain connections, hose, filter and sump), so this sensor-first step is our field triage, not an official Samsung sensor-first path: we meter and clean DD82-01373A before we ever quote a pump on that code.
• A classic 5E that is mechanical, not electrical: glass grit, a fruit pit, or a label gets past the filters and jams the DD31-00005A drain impeller. The motor coil reads continuity fine, but the rotor is locked, so the pump hums (or trips instantly) and water never moves. We pull the pump, fish the volute clear, and only replace it if a vane is chipped — a jammed-but-good pump just gets cleared, which is the honest call here.
• OC / 0C / oE is Samsung's over-level-water code — Samsung Canada describes it as 'excessive water, often linked to drainage problems' — so it overlaps the 5E drain family directly: the unit senses too much water and parks to avoid flooding. The same root causes apply — a restricted drain hose, a stuck or scaled DD82-01373A overflow sensor, a weak drain pump that can't pull the tub down, or an inlet valve not shutting off fully. We split the inlet/level side from the drain side before touching a part; on the drain side it's typically the same DD31-00005A pump, not the main board.
• A Samsung-specific no-drain that is NOT the pump is the check valve in (or just behind) the drain hose. Samsung puts a check valve near the pump-to-case-break connection to stop drained water siphoning back; when it jams shut or only partially opens, the unit can't push water out and the code follows. We pull the filter/sump cover, free or replace the check valve, and confirm it seats and moves freely before ordering the DD31-00005A.
• Weak drain-down between fills with no hard 5E points at the wrong pump: the DD81-01640A circulation/wash pump motor (x-ref PS10067144 / IC-77225SSDWB-1) delivers water to the spray system and is a separate motor from the drain pump on this platform. Note the current drain pump number is DD31-00005A while the circulation pump is DD81-01640A — they are NOT interchangeable and fail with different symptoms, so we separate a tired circulation pump from the DD31-00005A drain pump on the bench by function and never throw a drain pump at a wash-motor fault.
• Install-side no-drain with no failed part is common on Samsung: a kinked or sagging drain hose, no high loop / no air gap under the counter, or — on a new disposer — the factory knockout plug never punched out. With the knockout in place the dishwasher pumps against a dead end and parks with standing water; with no high loop, dirty sink water siphons back. We re-route the hose, set the high loop, or knock out the disposer plug instead of selling a part.

Samsung not draining / standing water in Toronto — the local specifics

• The recurring Toronto pattern on Samsung not-draining is the two-step trap: an owner (or another shop) swaps the drain pump on a 5E, the code clears for a few cycles, then returns — because the real fault was the DD82-01373A overflow/level sensor scaling up on local hard water, or a check valve / sump clog that was never cleared. We see the same DW80 families (DW80K5050, DW80R506x, DW80J3020) repeatedly, and the honest fix is to triage the level sensor and drain path first rather than reflex-replace the pump.
• We roll to these calls carrying the DD31-00005A drain pump (covers the superseded DD81-01527A), the DD82-01373A case-break/overflow water-level sensor, plus drain-hose / check-valve and replacement filter/sump-screen items — the set that lets us close a Toronto 5E/OC drain call in one visit instead of a parts round-trip.
