Bosch Dishwasher Repair in Toronto — Not draining / standing water

• E25 is the drain-pump fault: the controller can see the pump is commanded but flow isn't moving — most often a jammed impeller (a seed, a chunk of glass, a detached label) or a pump cover that isn't fully clicked down. We pop the cover, clear the impeller, and only replace the drain pump (00642239) when the motor itself is seized or open. The cover-not-seated version is a no-parts fix we verify every time.
• E24 is the 'water can't get out' fault — the drain path is restricted, not the pump dead. On Bosch this is the filter cylinder, the micro pump filter (00645038), the pump-cover area, or a kinked/clogged drain hose. We clean the sump and swap the micro filter (00645038) when it's grease-loaded; E24 and E25 are siblings and we always check both ends of the path.
• E22 is the upstream cousin of the drain codes: filter blocked / residual water sitting in the sump under the filter. Bosch has no food grinder by design, so a neglected filter loads up and water can't clear — the controller raises E22. Often this is owner-maintenance plus a micro pump filter (00645038) replacement, not a pump job, and we demo the monthly filter clean on the way out.
• Standing water that returns after every cycle with no error is the classic check-valve fault: the one-way valve in the drain line (00165262) has debris-jammed or worn, letting drained water siphon back into the tub. We pull the valve, clear or replace it (00165262) — a cheap part that's the difference between 'drains fine then refills' and a true pump failure.
• A continuously-running drain pump paired with E15 is the anti-flood lockout, not a drain blockage: water has reached the base pan and the float switch has parked the machine while the pump empties it. On a not-draining call this is the tell that the real problem is a leak, not the drain path — we find and dry the leak first, then reset. Never reset E15-and-pump-running blind.
• On a brand-new condo install that 'won't drain' from day one, the cause is almost never the dishwasher: the garbage-disposer knockout plug was never punched out, so the drain hose dead-ends into a sealed inlet. Two-minute fix, no Bosch parts — but it presents identically to E24/E25, so we confirm the knockout and the high-loop before quoting any pump or filter.

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

• The recurring Toronto pattern on Bosch not-draining is the E24/E25 pair on machines with no food grinder and a long-neglected filter — owners don't realize Bosch filters are monthly-clean items, so the sump and micro filter load with grease and the drain path chokes. The second recurring pattern is a check-valve refill (water drains then siphons back) on older units, and the third is the brand-new-install knockout/high-loop miss in condo kitchens — three distinct stories that all arrive as 'my Bosch won't drain.'
• We roll to Bosch not-draining calls carrying the drain pump (00642239), micro pump filter (00645038), and inline check valve (00165262), plus the tools to pop the pump cover and clear a jammed impeller on the spot. That kit closes the great majority of E22/E24/E25 calls in one visit; for a confirmed E15 base-pan lockout we switch to leak-finding first and reset only after the pan is dry.
