Bosch Dishwasher — Error Codes
| Code | What it means | Urgency |
|---|---|---|
| E15 |
AquaStop / Base Pan Leak Detection
Water detected in the bottom safety tray. The safety switch is triggered, forcing the drain pump to run continuously.
|
High |
| E24 / E25 |
Drain Fault / Pump Blocked
Dishwasher is unable to drain water properly. Check filter system, drain hose kink, garbage disposal knockout, or pump impeller.
|
High |
| E09 / E11 |
Heat Pump / Heating Element Error
Control board detected a open circuit or fault in the heating element integrated into the wash motor (heat pump).
|
Medium |
| E14 / E18 |
Water Fill / Flow Meter Fault
Water fill flow meter error or water supply inlet restriction. Control cannot calculate exact water quantity filled.
|
Medium |
| E22 |
Micro-Filter Clogged
Sump filter mesh is blocked with food debris, restricting water circulation and slowing drainage cycles.
|
Low |
An "E15" code on Bosch 300, 500, or 800 Series dishwashers usually means water has collected in the base tray. Tringing the dishwasher forward at 45 degrees drains the water and temporarily clears the code, but the source of the leak (sump seal or water inlet valve) must be identified.
Signs your Bosch dishwasher needs a professional
- Drain pump humming continuously even when door is open and power button turned off
- Error code "E09" resulting in cold wash water and wet, un-sanitized dishes
- Water tap symbol illuminated on display alongside E14 or E18 code
- Blinking cycle status LED that does not clear after a 3-second Start button reset
Bosch Washing Machine — Error Codes
| Code | What it means | Urgency |
|---|---|---|
| E18 / F18 |
Drain Time Out / Pump Filter Blocked
Tub failed to drain within set time limit. Clogged coin trap, obstructed drain pump impeller, or kinked drain hose.
|
High |
| E17 / F17 |
Water Supply Time Out
Water fill time exceeded maximum limit. Check house shutoff valves and inlet valve screen filters.
|
Medium |
| E23 / F23 |
AquaStop Leak Detection Activated
Water sensor in bottom tray triggered. Water inlet safety valves close automatically to prevent flood.
|
High |
| E32 / F32 |
Unbalanced Load Detected
Washer reduced or aborted high-speed spin cycle due to unbalanced distribution of laundry in drum.
|
Low |
| E21 / F21 |
Motor Drive / Carbon Brush Circuit Fault

|
High |
Bosch compact washers with "E18" or "F18" can be drained using the small emergency drain tube located behind the lower front maintenance flap before unscrewing the pump filter cap.
Signs your Bosch washing machine needs a professional
- Door latch remaining locked shut with clothes and water stuck inside drum
- Heavy grinding sound during high-speed spin (spin tub bearing failure)
- Display locked on "F21" or "E21" error requiring a hardware reset sequence

| DR / DR DRAIN |
Condensate Tank Full / Drain Pump Error
Water condensation drawer is full or internal condensate pump is blocked/failing.
|
Low |
Bosch condensation and heat-pump dryers (500/800 Series) don't vent outside. If you get a "DR" error or laundry takes hours to dry, pull out the lower heat exchanger unit and wash the fins thoroughly under running water.

Bosch Repair FAQ
How do I reset my Bosch dishwasher error code?
Press and hold the Start button for approximately 3 to 5 seconds until the display shows "0:01" or "0:00". Close the door and wait for the 1-minute drain cycle to complete. For persistent codes like E15, perform a hard reset at the home circuit breaker.
Why is my Bosch dishwasher showing E15 and running non-stop?
The E15 code indicates water in the bottom safety pan. The AquaStop system activates the drain pump to prevent flooding. The leak source must be cleared and base drained before normal cycle operation can resume.
What does error code E18 mean on a Bosch washing machine?
E18 indicates a drain fault. This is typically caused by a clogged drain pump filter trap at the bottom front corner, a blocked drain hose, or foreign objects stuck in the pump impeller.
Are original Bosch OEM replacement parts used for repairs?
Yes, all Bosch appliance repairs are completed using original Bosch factory OEM replacement parts to ensure precise fit, performance, and reliability.
