Code IE
low severity
Bosch models: Bosch dishwashers have a three-stage filter: coarse screen, flat micro-filter, and cylindrical fine filter under the lower spray arm. Remove and clean all three together. Bosch drains actively using a pump — any standing water in the sump at mid-cycle is a blockage indicator, not normal residual water.
Common causes
- Water supply valve (under the sink) closed or partially closed
- Inlet hose kinked
- Inlet mesh filter on the machine clogged with sediment
Step-by-step fix
- Verify the shut-off valve is fully open.
- Inspect the inlet hose for kinks.
- Shut off water, disconnect the inlet hose at the machine, and pull the small mesh filter out with pliers — rinse and reinstall.
- Restore water and run a rinse cycle.
