Resolving Constant Fill/Drain Loop & Replacing Circulation Pump on an Electrolux Dishwasher
Dishwasher constantly draining
## The Problem
The client contacted us after their Electrolux dishwasher became unusable due to an endless cycle loop. The machine would fill with water, immediately drain itself, and start filling again without ever advancing to the actual wash phase. ## Diagnostics & Multi-Stage Findings
Our specialist diagnostic process uncovered two distinct issues—a primary obstruction causing the cycling loop and a secondary hardware failure preventing wash circulation:
1. **Pressure System Check:** We inspected the water level sensing system. Debris and buildup in the pressure chamber were causing false signals to the control board, misreporting the internal water level and forcing the drain pump to engage continuously in a safety loop. 2. **Cycle Test & Motor Diagnosis:** Once the pressure system was cleared, the dishwasher filled correctly. However, the machine remained completely silent during the wash stage. Testing power to the main wash motor confirmed voltage was present, but the **circulation pump had completely seized**, preventing water from spraying through the wash arms. ## The Repair Process
To ensure a long-term fix and restore full performance, we executed a comprehensive repair strategy:
* **Pressure Chamber Service:** Thoroughly cleaned and flushed out the pressure chamber assembly, clearing all debris to restore accurate water level sensing. * **Pump Replacement:** Disassembled the lower housing assembly, removed the seized wash motor, and installed a brand-new **OEM Electrolux circulation pump**. * **Starter Capacitor Upgrade:** Replaced the starter capacitor alongside the motor to ensure smooth startup torque, prevent premature wear on the new pump, and improve overall longevity. * **Full Electrical Inspection:** Using specialized testing gear, we conducted a full electrical inspection to ensure the machine met all safety compliance standards. * **Extended Operational Testing:** Executed a full test wash cycle, verifying water intake, wash arm spray pressure, heating performance, and complete drainage. ## Results & Impact
* **Appliance Saved:** Successfully prevented a costly total machine replacement by pinpointing and fixing both underlying mechanical issues. * **Extended Lifespan:** Replacing both the circulation pump and starter capacitor ensured long-term operational stability and reliability. * **Certified Safe:** Passed a full electrical safety audit, giving the customer complete peace of mind. ### Is Your Dishwasher Stuck in a Loop or Not Washing?
