Ow was working fine but now the "Low-on rinse air light" is ON even when filled. I have not adjusted the rinse aid dispenser rate. Seeing white deposits inside non-stick pans and on silicone handles. Is this more than a bad rinse aid level sensor?
For model number LDF7774WW
PartSelect logo
Hi Paul, Thank you for your question. If your rinse aid light will not turn off, the dispenser may have a leak in it. You will need to remove the dispenser from the door and check for any leaks. If there are no leaks, reset the dishwasher by turning the circuit breaker for a few minutes. We hope this helps!

Keep searches simple. Use keywords, e.g. "leaking", "pump", "broken" or "fit".
Broken door spring allows the door to overextend to the floor if not propped.
Simple, removed screws securing machine in the cabinet, then pull the unit out of the cabinet space about 10 inches. Springs are accessible within this extension. You need strong hands to extend the springs and attach them. Once attached, push machine back in place and re-install the anchor screws. In my situation, only one spring was broken, so the attached side revealed the correct slot to place the hook on the top position, the bottom position has a plastic lead for the spring, and that lead is attached to a rope to the door hinge. Note: Replace BOTH springs, even if only one is broken.

First do not watch the videos . They had you taking the insides all apart
when all you had to do is pull the unit out , twist the motor out and put the new one back in. Take nothing apart inside the dishwasher.
