Common Signs of WD21X802 Drain Solenoid Failure and How to Diagnose Them
When a WD21X802 drain solenoid begins to fail, several noticeable symptoms can surface, frequently enough disrupting your appliance’s normal operation. One of the most common signs is the failure of water to drain properly during cycles, causing your washing machine to stall or leave clothes soaking wet. Additionally, you might hear unusual clicking or buzzing noises every time the machine attempts to trigger the drain mechanism.Another indicator is intermittent draining where the appliance occasionally empties but doesn’t complete the cycle smoothly.
Diagnosing these issues involves a few straightforward steps. Start by ensuring power is reaching the solenoid and checking for any obvious physical damage or corrosion around the electrical connectors. Using a multimeter, you can test the solenoid’s coil resistance to confirm if it’s within manufacturer specifications. If the coil shows an open circuit or unusually high resistance, it’s a clear sign of failure. Visual inspection of the drain valve can also reveal if it’s stuck or obstructed, which can mimic solenoid malfunction. below is a rapid reference table for coil resistance values:
| Solenoid Model | Expected Resistance (Ohms) |
|---|---|
| WD21X802 | 20-30 Ω |
