Who repairs Bosch dishwashers in Toronto? N Appliance Repair does. Call (437) 524-1053, available 7 days a week. We've been servicing Bosch appliances across Toronto — including North York, Scarborough, Mississauga, and Etobicoke — since 2017. Bosch makes some of the quietest, most efficient dishwashers on the market, but their sophisticated engineering also means a wider range of potential failure points compared to simpler machines.
Quick Answer: The most common Bosch dishwasher issues are the E15 flood protection error (water in the base) and E24 drain fault (clogged filter or hose). Toronto repairs cost $170–$340 CAD including parts and labour — call (437) 524-1053 for same-day service.
What Are the Most Common Bosch Dishwasher Error Codes?
Bosch uses a specific error code system displayed on the control panel or through a sequence of flashing lights depending on the model. Understanding these codes helps you describe the problem accurately when you call us — and sometimes reveals whether a quick DIY fix is possible before a technician visit.
- E15 — Anti-flood protection activated. Water is sitting in the base tray and has triggered the Aquastop float switch. The machine will lock itself and refuse to run. Do not use until inspected.
- E24 / E25 — Drain fault. The dishwasher cannot complete draining. E24 is the most common code we see on Toronto service calls. Check the filter and drain hose first.
- E09 — Heating element fault. The water is not reaching wash temperature. Usually a failed heater element or a bad NTC thermistor.
- E01 / E02 — Control module errors. Often require a board-level repair or replacement.
- E22 — Clogged filter. The machine senses restricted water flow through the filter. Remove and clean the filter assembly.
- E27 — Low voltage supply. An electrical supply issue rather than a dishwasher fault; check your breaker panel.
What Causes the Bosch E15 Error and How Is It Fixed?
The E15 error is Bosch's Aquastop system doing its job — detecting a leak before it damages your kitchen floor. When water enters the drip tray at the bottom of the machine, a polystyrene float rises and trips a microswitch. The machine cuts power to the inlet valve and displays E15.
Fixing it properly involves two steps: draining the base tray (by tilting the machine 45 degrees onto its side to let the water run out), and then finding and repairing the actual leak source. Common leak origins include a cracked sump, a loose hose clamp, or a deteriorated door gasket. Our technician Sofia C. notes that in Toronto condos where Bosch dishwashers are installed under stone countertops, the tilt step is particularly important — simply mopping the tray and running the machine again will result in E15 recurring within days.
What Causes the Bosch E24 Drain Error?
E24 is a drain fault and is the error code we are called about most often for Bosch dishwashers in Toronto. The diagnostic pathway typically runs through these causes in order:
- Clogged drain filter (most common — clean it first)
- Blocked or kinked drain hose
- Garbage disposal knockout plug not removed (on new installations)
- High drain loop not installed correctly
- Failed drain pump motor

How Does Our Bosch Dishwasher Repair Process Work?
Read the error code and listen to the customer
We note the displayed error code and ask about the sequence of events leading up to the failure — unusual noises, leaks noticed, recent cycle changes.
Inspect filter, spray arms, and drain path
We clean and inspect the full filter assembly, check all spray arm jets, and trace the drain hose from the sump to the sink connection or garbage disposal.
Inspect base tray for water (E15 cases)
We tilt the machine to check for pooled water in the base tray. If found, we identify the source before proceeding with any repair.
Test electrical components
Pumps, valves, thermistors, and the heater element are tested with a multimeter for correct resistance values per Bosch service specifications.
Replace failed parts and verify with a full cycle
OEM or OEM-equivalent Bosch parts are installed. We run a complete wash and drain cycle before sign-off.
Warning: If your Bosch dishwasher displays E15, do not attempt to reset it and run another cycle. The water in the base tray will be pumped around the machine's electronics each time it operates, potentially causing permanent control board damage or an electrical hazard. Disconnect power and call a technician.
