Having problems with your Bosch Dishwashers ?

Whatever program is used - the lower rotating arm only produces water and the program will not advance from that.


Answers :

It is possible that the machine does not start off the cycle because there are errors or back feedback from the inputs. For the program to start up the main program controller must initiate the INLET valve to open up and allow water to flow into. If this does not happen then the voltage at the inlet valve must be checked or the fault relates to no voltage from the controller. This means the controller is a suspect.
\012

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor .
\012

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the drain valve/pump activated so as to drain off all the water .
\012

Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.

We have a Frigidaire dishwasher model #FDB634RF bought new. It was used for a not very long period of time but developed problems due to well water with high lime content. now with good cleaning products available it is ready for use again. The problem is the top spray arm that refuses to rotate. I have taken the arm out and thoroughly cleaned it of deposits checked the supply line from the pump and checked the sump for any obstruction.

Kenmore model#587(Frigidaire) leaks under door. New install. Had machine for a year plus before install. took off front panel- can see water squirting past lower door gasket as wash arms rotate. cause is water running down door during wash cycle piles up in the channels molded into the lower left & right side of the wash tub and pushes out the sides of the lower gasket. looks like a design issue- called SEARS, they just want to sell me a new gasket! go figure. any ideas on a fix?


It does sound like an inner door seal ,however If you get upset at Sears and complain they may help you as they say the squeaky hinge gets the oil..And with Sears the more you squeak the better your chances of results ...Good Luck ... Dishwashers

I have a Frigidaire dishwasher, FDB-1100RHC, that is not cleaning dishes. My fiance cleaned the trap at the bottom of the washer, removing both the small basket and the larger mesh grid. After replacing both, the washer doesn't seem to have enough water pressure to spin the lower and/or upper arms. If I interrupt a cycle and open the door, water is dribbling out of the upper arms, but they are not rotating and do not move from whatever position you place them in. Both arms are completely uno

Noticed dishes on top shelf not entirely clean. Ran machine empty and opened many times during wash. Noticed that Lower Spray Arm works as expected, but Middle Spray Arm turns only 1/8 or less, then Lower Arm spins again. Schematic with Use and Care manual just says pump motor switches from one to the other in certain cycles, but I don't see this happening. Looked for obstructions to water flow and pressure seems normal. Is control for this function part of the pump, or in the control panel?

I had a service tech at my house to repair my refrigerator. He also took a look at my Maytag WU504 dishwaser, which was not cleaning the dishes anymore. He was less familiar with dishwasher diagnosis, but found that the lower spray arm was pumping out water through the jets properly in the cycles, but that the spray arm was not rotating. He seemed stumped and called his supervisor, who suggested it might be the wash impeller. I have looked at the parts diagram on partselectdotcom and taken t

Bosch dishwasher lower washer arm not rotating


... Bosch Dishwashers

The dishwasher has three arms in it. The top and bottom arm do not rotate. The middle arm rotates fine. The arms will move when manually munipulated but do not spill while the dishwasher is on. There was a loud grinding the first time the dishwasher was used and it seemed to work fine but after about two months of use the arms will not rotate.


Sounds like maybe some rinsing salt was spilled when the salt reservoir was filled the first time (or broken glass, this always used to be an issue in catering) and got pumped through, lodging in the gap between the arm and it's mounting. this can ro ... Maytag Dishwasher

Bosch SHU4302 WITH REPAIRED PC BOARD has been working fine for several years now seems stuck in rinse/drain mode and is not quite pumping cabinet dry. I have removed the screens and located the small impeller at bottom below cover. The impeller rotates as though it has multiple spring loaded stop positions. When I turn on the unit and open the door water is trickling from the sprayer arms at low pressure. It seems stuck in rinse mode and will not advance cycles or reset when shut off.

Hi there I've got a Miele G572 dishwasher that works perfectly, except that it trips the circuit breaker when it tries to fill with water. The heating works, the timer advances, the spary arms rotate and it drains well. It is a second-hand unit that worked for about 3/4 of the first cycle, then it tripped the earth leakage detector.
