How to Fix / Troubleshooting
Safety: Disconnect power before working on the drain system. Water may spill when hoses are removed.
Drain troubleshooting:
- Inspect drain outlet: Locate the drain hose at the rear or base. Ensure it is not kinked or elevated above the recommended height.
- Clear blockage: Detach the hose and flush it with warm water to remove ice or debris. Use a flexible brush if necessary.
- Check pump: Access the Siemens drain pump (usually at the base). Inspect for foreign objects in the impeller housing. Remove any obstructions.
- Test pump motor: With a multimeter, check for continuity of the pump motor. If open or seized, replace the drain pump assembly.
After repair: Reassemble, restore power, and run a test cycle to confirm proper draining.
