Bosch Error Codes — What Your Dishwasher or Appliance Is Telling You
Bosch dishwashers are the most common appliance repair call we receive in Berkeley. The E-code system is specific and informative — each code points to a distinct system. This guide explains every Bosch error code, what it means, what to try, and when to call for same day repair.
Why Bosch displays error codes
Bosch dishwashers run continuous self-diagnostics. When a fault is detected, the display shows an E-code and the cycle stops. This is a feature, not a design flaw — it prevents equipment damage and tells you exactly what has gone wrong.
Bosch Dishwasher Error Codes — Complete Table
These codes apply to all Bosch dishwasher series: 100, 300, 500, 800, Benchmark, and Ascenta. Bosch's BSH-platform siblings (Thermador and Siemens) use the same code system.
| Code | Fault system | Plain language | Try at home | Severity |
|---|---|---|---|---|
| E01 | Control board | Main control board fault. The board controlling the appliance has detected an internal error. | Reset by turning off the circuit breaker for 60 seconds. If E01 returns, the control board requires replacement. | Call for diagnosis |
| E09 | Heating | Heating element or heater relay fault. Water is not being heated to the required temperature. | Reset. If E09 returns after one cycle, the heating element or relay has failed. | Repair — dishes not sanitizing |
| E15 | Flood protection | Water in the base pan. The flood sensor has detected water under the dishwasher and activated the shutoff. | Stop use immediately. Tilt the dishwasher slightly forward to drain the base pan (you'll need to disconnect power first). Call for the leak source diagnosis. | Stop use — call same day |
| E17 | Water inlet | Water pressure too high. The supply water pressure exceeds Bosch's inlet valve design range. | Check household water pressure. Bosch dishwashers are rated for specific inlet pressure ranges. | Plumbing or valve diagnosis |
| E18 | Water inlet | Water inlet fault. The dishwasher is not filling with water at the expected rate or volume. | Check that the water supply valve under the sink is fully open. Check the inlet hose for kinks. | Call if supply is open and still not filling |
| E22 | Filtration | Filter blocked. The fine filter or mesh filter at the bottom of the tub is clogged. | Remove and clean the filter assembly at the bottom of the dishwasher. Rinse under running water. E22 is the only Bosch code you should always clear yourself before calling. | Clean filter first — may resolve |
| E24 | Drain | Drain fault. The dishwasher is not draining within the programmed time after a cycle. | Clean the drain pump filter. Check the drain hose for kinks. Run a drain program. If E24 persists, the drain pump motor has failed. | Call if filter cleaning doesn't resolve |
| E25 | Drain | Drain pump blocked. The drain pump impeller is blocked by a foreign object — commonly a small bone, olive pit, or piece of glass. | After cleaning the filter, access the drain pump impeller through the filter compartment. Remove visible debris. If blocked but not freely spinning, call for pump clearing. | Call if impeller blocked by debris |
| E27 | Power supply | Voltage supply issue. The dishwasher is detecting insufficient or unstable power supply. | Check the circuit breaker. Confirm the dishwasher is on a dedicated 20A circuit. Call an electrician if voltage is suspect. | Electrical diagnosis |
Bosch E15 — Stop Use Immediately
E15 means water is in the base pan under your dishwasher. Continuing to run the appliance can cause floor damage and electrical hazards. Turn off the dishwasher and the water supply valve under the sink. Call Fast Help at {PHD} — we repair Bosch E15 same day in Berkeley.
Bosch Oven Error Codes
| Code | Meaning | Action |
|---|---|---|
| E005 | Temperature sensor (NTC) fault. The sensor measuring oven cavity temperature has failed. | Reset. The oven will not heat correctly with a failed NTC. Call for sensor replacement. |
| E011/F011 | Control panel button stuck or shorted. A key is continuously registering a press. | Check for moisture or debris around the buttons. Dry the panel. If fault persists, the control panel requires replacement. |
| E109 | Door lock fault. Self-clean mode door lock is not engaging or disengaging correctly. | Do not force the door. Reset. If the door is locked and won't open, call — this is a latch motor fault. |

Bosch Washer and Dryer Error Codes
| Code | Meaning | Action |
|---|---|---|

| E23 | Drain pump fault (washer). The drain pump is not operating correctly. | Clean the pump filter first. If E23 returns, the drain pump motor requires replacement. |
| E32 | Pressure sensor fault. The water level sensor is reading incorrectly. | Reset. If E32 returns, the pressure switch or hose requires diagnosis. |
