On Bosch dishwashers, E24 means water isn't draining (usually the filter, drain hose or disposal connection), E25 means the drain pump is blocked or failing, E22 means a clogged filter, E15 means water reached the base and leak protection stopped the cycle, E09 means a heater problem, and E14, E16 and E17 point to water-fill problems. Clean the filter and check the hoses first; E15 that won't clear, E09 and repeat drain codes need a technician.
| Code | What it means | What you can do |
|---|---|---|
| E24 | Water didn't drain at the end of the cycle | Clean the filter, check the drain hose and disposal knockout plug. |
| E25 | Drain pump blocked or faulty | With power off, check the pump cover under the filter for glass or debris. Repeats need a pump. |
| E22 | Filter blocked | Clean the filter and sump. |
| Code | What it means | What you can do |
|---|---|---|
| E15 | Water in the base — leak protection activated | Find the leak (door seal, hoses, oversudsing). The base must be dried before it runs; call if it returns. |
| E14 | Water flow / fill (flow meter) problem | Check the supply valve and inlet hose. Repeats need diagnosis. |
| E16 / E17 | Water can't enter or fill correctly | Make sure the inlet hose isn't kinked or damaged and the supply valve is fully open. |
| Code | What it means | What you can do |
|---|---|---|
| E09 | Heater problem | Technician repair (heater pump, heater or control). |
| E21 | Meaning varies by model — sources give different definitions (wash/heat pump or drain pump) | Model-specific: a technician visit is needed to find the exact cause. |
Codes and their meaning can vary by model and production year, and the same code can have different causes. Where sources disagree we say so; in every case the exact cause is confirmed only by a technician's on-site diagnosis. Your owner's manual has the definitive list for your model.
Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.
Find and fix the leak, then dry the base pan; the code won't clear while water is there. Call us if you can't find the source.
The dishwasher couldn't drain — start with the filter and the drain hose.

A 38-year-old Sub-Zero 500 Series freezer most companies would have written off: we replaced the compressor, evaporator, heat exchanger and drier with OEM parts and retrofitted it from R12 to a modern refrigerant.
