Almost every Bosch call we take is a dishwasher, and almost every dishwasher fault is about water going somewhere it should not. The codes make the diagnosis unusually direct. These are the ones that come up.
The Issues We See Most
- E15 anti-flood trips from leaks under the tub.
- E24 drain faults from clogged pumps and filters.
- E09 heating faults that leave dishes wet.
- E22 filter blockages that hold water.
- Inlet-valve and fill faults.
- Control-board failures after power events.
Symptom, Cause, and Fix
Each Bosch code below names a specific water fault, with the usual cause and what it takes to clear it:
| Code | Usual Meaning | What It Takes to Clear It |
|---|---|---|
| E15 | Water in the base pan, anti-flood float tripped | Find and stop the leak; dry the pan and reset the float |
| E24 | Drain fault, clogged filter, pump, or hose | Clear the filter and drain hose; replace the pump if needed |
| E22 | Filter or drainage blockage, water not clearing | Clean the filter and check the drain path |
| E09 | Heating element or flow-through heater fault | Replace the heating element or heat pump |
| E01 | Electronic control-board fault | Reset power; replace the control board if it repeats |
Repair or Replace?
Bosch dishwashers are economical to repair. Drain pumps, inlet valves, and float switches are inexpensive and widely stocked, so the repair rarely approaches the cost of a comparable replacement. We quote it in writing first.
How We Work Through It on Site
Bosch dishwasher codes are among the clearest in the industry, and they reward being read literally. E15 means the base float has tripped on water, so we find the leak instead of drying the pan and calling it done. E24 and E22 are both restriction complaints, and the filter, the impeller, and the drain hose account for most of them, often with no part needed. E09 points at the heating circuit, which we confirm with a continuity test across the element. Because the codes are this specific, a correct Bosch diagnosis rarely requires guesswork.
What You Can Catch Early
Pull the filter monthly and rinse it. That one habit prevents a meaningful share of the E22 and E24 calls we take across Colorado Springs. If dishes are coming out cooler than usual or drying poorly, the heating circuit is drifting and an E09 is often next. Machines that run longer than they used to are compensating for something. And if you have had a surge event in the house, mention it, because Bosch control boards do fail after power disturbances and the history shortens the diagnosis.
