The spray arms on my GE Triton dishwasher no longer spin. Is this due to lime build up on the insides of them or is it a low pressure problem with the pump? Would replacing the spray arms help?
ANSWER Hello Rae,
This is probably due to the flapper seal failure. I looked at several models and it appears that the sump assembly that contains the flapper is no longer available. In this case, the only way to restore normal operation is to replace the complete pump and motor assembly. The spray arms will not help at all. You see, the flapper directs the water flow to either drain or recirculate. When the flapper seal fails, it cannot put all of the pressure in either direction, so it will not circulate correctly and it will also not drain completely.
This is actually caused by rinsing the dishes and over soaping. Think of it this way: The dishwasher creates a chemical reaction by raising the detergent temperature to 140°F. When the chemical reaction takes place, the easiest thing for the chemical reaction to attack is food particles. If the unit was over soaped, there is too much chemical reaction taking place plus if the dishes were rinsed, there are no food particles to occupy the chemical reaction. This makes the chemical reaction attack the next easiest thing to attack, which just happens to be the rubber seals in the dishwasher, the cheaper glassware, (etching), and the patterns on the plates.
So you see, the dishwasher is a chemistry experiment, with clean dishes being the desired result. If misused, the desired result cannot be obtained.
