  Joseph KingAug 18, 2025
  If the Electrolux Dishwasher wash tank isn't filling completely, several factors could be at play. First, ensure the wash tank water supply cock is open. Then, check if the water load solenoid valve is functioning correctly; if not, replace it. Also, verify that the water feed flow is adequate and that the water inlet filter is clean. Other potential issues include a malfunctioning pressure sensor on the wash tank or wash board, an uninserted wash tank overflow, or a faulty wash tank drain solenoid valve that remains open. Finally, the wash board itself may not be working correctly, so consider checking or replacing it.

  If the Duo-Rinse tank in your Electrolux Dishwasher isn't filling completely, several factors could be the cause. First, check if the impeller rotation is correct. There may be a leak in the plumbing circuit connecting the air gap to the rinse jets, or a leak in the CU, so fix any leaks you find. Also, the non-return valve on the air gap may not be working properly and should be checked or replaced. Ensure the DUO tank overflow is inserted. Furthermore, the Duo drain solenoid valve may be faulty and remaining open, so check or replace it. Lastly, the pressure sensor on the rinse board or the rinse board itself may not be working correctly; check or replace them as needed.

  Joseph JonesAug 23, 2025
  If your Electrolux Dishwasher boiler isn't reaching the required temperature, it could be due to several reasons. The rinse water flow might be too high, so try reducing it. A heating element or branch may not be working correctly and needs to be checked or replaced. The CU might be dirty and require cleaning. Additionally, the boiler temperature sensor or the boiler heating element starter controller (or its coil connection to the rinse board) could be faulty, requiring inspection and potential replacement.

  Stephanie FowlerAug 28, 2025
  If the water temperature in the Duo-Rinse tank of your Electrolux Dishwasher is too high, it could be due to a change in the “Duo temper.” parameter settings, so check them. Alternatively, the relay that activates the Duo rinse heating element starter controller might be stuck, so check the relay.

How to fix an Electrolux WTCS90ERB Dishwasher air gap that isn't filling?
- S
  Sonya CookSep 4, 2025
  If the air gap in your Electrolux Dishwasher isn't filling completely, start by ensuring the air gap water supply cock is open. If that's not the issue, the water filling solenoid valve may be malfunctioning and require checking or replacement. Also, check if the water feed flow is too low and increase it if necessary. A clogged water inlet filter can also cause this problem, so clean it. Lastly, a faulty boiler pressure sensor could be the culprit, so consider checking or replacing it.
