GE Dishwasher Repair in Toronto — Not draining / standing water

• The C1 / C2 / C3 drain codes are GE's own drain-timer logic and they tell us where in the drain path to look. C1 latches when the pump cannot clear the tub within about 2 minutes (120 seconds) — a partial restriction such as the filter, sump, or a kinked hose; C2 latches when it cannot drain within the ~405-second maximum (a total blockage — clogged hose, plugged air gap, or a seized pump); C3 is the terminal 'will not drain' state — a complete drain failure where pump-out is never accomplished (some references also list it as an inoperative drain sensor). We read which of the three latched before we touch a part, because C1 is almost always a cleanout and a hard C3 with a clean drain path points at the pump or its electrical side.
• The single most-replaced not-draining part on this platform is the WD26X22719 drain pump kit, and it is sold as an assembly that includes both the drain pump and the float switch. It supersedes the older WD26X10023 / WD26X10043 / WD26X10040 (and factory number 165D8193G005), so one current part covers the whole GDF/GDT/PDT/CDT generation. We confirm it the right way before condemning it: a pump that hums but leaves standing water usually has a debris-jammed impeller, and we spin the impeller and check the windings for continuity — a dead pump reads open and gets the WD26X22719, a jammed-but-good pump just gets cleared.
• A classic GE-specific standing-water cause that is NOT the pump is the sump check valve. GE puts a check valve (WD12X25476, plus the related older GE check-valve part WD12X10189) under the filters at the sump to stop drained water from siphoning back into the tub. When it sticks closed the unit cannot push water out (drain codes follow); when it sticks open, water the pump just expelled flows back and the tub never empties. We pull the filter and sump cover, free or replace the check valve, and verify it seats and moves freely before we order a pump.
• On any unit that has just been installed or had a new garbage disposal fitted, a C2 'totally blocked' no-drain is very often the disposer knockout plug — the solid plastic web inside the disposal's dishwasher inlet nipple that the installer never punched out. Water has nowhere to go, so the dishwasher pumps against a dead end and latches. This is a 10-minute fix (knock the plug out, retrieve it from the disposer) and we always rule it out first on new-install calls before any part is quoted; GE itself ships this step in its own drain-code troubleshooting.
• The filter, sump, and the drain hose are the C1 partial-restriction trio. Food soil, glass grit and grease collect in the fine filter and the sump cavity below it, and on the corrugated drain hose the low point under the sink traps sludge or kinks behind the cabinet. We clear the filter/sump and snake or flush the hose; a genuine C1 that returns clean after a cleanout does not need the WD26X22719 — we only replace the pump when the impeller or motor itself has failed.
• A no-drain that is really a no-start hides behind the door latch. The WD13X10003 latch-and-switch assembly tells the board the door is closed; when the micro-switch wears, the board never enters the cycle, so the unit sits with water in it and looks like it 'won't drain' when in fact it never advanced to the drain step. We separate the two on site — lights-on-but-dead-with-water points at the WD13X10003 latch switch, not the drain pump.
• An air-gap or high-loop install fault produces intermittent standing water with no failed part. GE's own installation spec requires the drain hose to either run through a sink air gap or be secured in a high loop above the flood rim to stop the sink drain from siphoning waste water back into the tub. A clogged air-gap cap or a hose that has slipped down off its high loop lets dirty water flow back after each drain, so the dishwasher reads as 'not draining' when the cure is clearing the air gap or re-securing the loop — we inspect the under-sink routing before condemning any GE part.

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

• The recurring GE-in-Toronto not-draining pattern is that the code points one of two completely different ways and we sort it on the threshold: C1 partial-drain tickets are overwhelmingly a filter/sump/check-valve cleanout (often the WD12X25476 valve stuck or scaled), while C2/C3 are the real pump or a dead-end install — and on freshly installed or new-disposal units the C2 'no drain' is repeatedly just an un-punched disposer knockout plug, not a failed part. We also keep catching humming-pump calls where the impeller is jammed with glass grit, which we clear rather than replace.
• We roll to GE not-draining calls carrying the WD26X22719 drain pump kit (pump plus float switch, supersedes the older WD26X10023/10043/10040), the WD12X25476 sump check valve, and the WD13X10003 door latch, plus filter/sump cleanout tools and a spare drain hose — enough to clear a C1 cleanout, free or replace a stuck check valve, or drop in a pump on a C2/C3 in the same visit.
