  Michael WalterAug 21, 2025
  If your Nelson Washer isn't starting when you turn it on, several factors could be at play. First, check if there's voltage in the electrical system, ensure the main switch is connected, and verify that the fuses are intact. The machine's connecting cable might be damaged and need replacement. Also, inspect the conductors in the control panel terminal board, and tighten them if they're loose. The machine line switch or conductor contacts may be inefficient and require replacement. The door micro might be faulty, so replace it if necessary. Finally, check the connection of the electronic board, and replace the board if necessary.

  If your Nelson Washer isn't rinsing, check these potential issues: Ensure there's water in the system and the tap is fully open. Inspect the supply pipe for any bends or squeezes. Remove and clean the solenoid valve filter if it's dirty. If the solenoid valve coil is interrupted, replace it. Remove and check the small piston of the solenoid valve. Also, ensure the system pressure is at least 2 bar; if it's lower, consider installing an auxiliary rinse pump.

  Victor BauerAug 30, 2025
  If your Nelson Washer rinses continuously, it could be due to a dirty solenoid valve. Try removing the solenoid valve and cleaning the membrane compensation cutout, replacing the valve if it's sealed. The membrane may also be torn, requiring replacement. Additionally, the small piston might not be moving properly or is blocked, so check and replace the solenoid valve if needed. Finally, check the connection of the electronic board, and replace the board if necessary.

  If the water in the boiler or bowl of your tri-phase Nelson Washer isn't heating up, here are some potential causes: A phase might be missing from the relay coil, so check it. The relay coil itself could be interrupted, also requiring a check. The boiler thermostat or pressure switch contacts might be faulty and need replacement. The relay contacts may be worn out, necessitating replacement of the contactor. Check the connections and conductors for faults. Ensure there isn't a missing phase in the appropriate circuit. The boiler heating element could be damaged and need replacement. Lastly, verify that the connection between the terminals and the heating element is correct.
