frigidaire dishwasher problem
Hi,
I have a 2 year old Frigidaire dishwasher (model number FDB710LCB0). Before I start, I have cleaned all the filters and checked for obstructions. Now, the problem is this: During the Heavy and Normal wash cycles, the upper spout, which supplies water to the middle arm does not produce enough pressure to spin the middle arm. The lower arm has fantastic pressure. Only during the Light wash cycle does the upper spout really spray well, but only for about 30 seconds or so. Under the filter there is a small plastic ball which sits next to the impeller blade. The ball appears to perform the function of alternately plugging up either the upper spout path or the lower spout path, to allow each arm to operate one at a time (this model is supposed to have the two arms alternate spraying. I suppose the impeller is supposed to reverse direction (?) to cause the ball to travel back and forth on its ramp. I'm at a loss as to what is wrong. If I remove the ball, both arms work at the same time, but with reduced pressure on each arm reducing effectiveness. Any ideas? |

frigidaire dishwasher problem
I have a similar Frigidaire model purchased brand new this year. Under
warranty, I called Frigidaire who said that this behavior is normal. I insisted that something's wrong. Repair man came, and confirmed that this is the way it is designed. I even emailed Frigidaire customer service, who replied: "The arm comes on during the short wash cycle and alternates with the lower spray arm." So the upper arm is purposely inactive during Rinse and Hold, Pots&Pans, Regular Wash. It only activates during light wash and rinsing. As an engineer myself, I call this a bad design! My dishes do NOT come out clean unless I make absolutely sure they're well rinsed before I put them in. Anyone know if it's possible to change this (by any means possible) so that both arms alternate during EVERY cycle??? -Disgruntled Frigidaire Dishwasher Owner Jake wrote: I believe I am having the same problem. My model is FDB710LCQ0. I've pulled the dishwasher out from the counter to see if there was some type of visual blockage on the line running to the upper spout. I didn't find any blockage, but I did notice the pressure to the middle arm was extremely low. I disassembled everything down to the ball and impeller and the machine worked again for about 1/2 a cycle. There is an extreme difference in the water pressure running to the spout when it works properly (middle arm spins) versus when the arm doesn't spin. This makes me wonder if the motor is going bad. I would rather not spend $120 on a new motor. mark wrote: Hi, I have a 2 year old Frigidaire dishwasher (model number FDB710LCB0).
