  If the regeneration cycle isn't starting on your Nelson Washer, check if there's water in the water system and the tap is open. Ensure the supply pipe isn't bent or squeezed. Remove and clean the solenoid valve filter if it's dirty. Replace the solenoid valve coil if it's interrupted. Remove and check the small piston of the solenoid valve. Check all connections on the coil electric circuit. Also, check the connection of the electronic board, and replace the board if necessary. Check the connection and if necessary replace the push-button or the switch. Check the connection and if necessary replace the switch. Replace the coil.

  If water continuously enters the Nelson Washer, it might be due to several reasons. The solenoid valve could be dirty, requiring you to remove it and clean the membrane compensation cutout, replacing it if it's a sealed unit.

Other causes include a loose connection between the small tube and pressure switch (shorten the tube and re-insert it tightly), a pierced air trap or small tube (replace them), water in the pressure switch or air supply tube (remove and blow the water away, replace if needed), loss of pressure in the pressure switch (unload and reload the dishwasher), or a faulty pressure switch (...
