Arms not spinning---dishes not clean ---Maytag Quiet Series 300

Hello,

I suspect the impeller may not be moving enough water to properly rotate the spinner arms.

Diagnostic:

I first checked the inlet solenoid to insure hot water was coming in. I added more water by hand in case it was shutting off too soon. I then set each arm to a known positon. Bowls were placed on the top rack to catch water from the top spinner. I closed the door, then opened the door during wash or rinse. The arms would only sometimes be found rotated, and the bowls had little or no water in them.

I removed the bottom spinner assembly to check the impeller, and it is spinning during either cycle. I also ran the units self test, which indicated no problem (of course!). Do I have a bad motor or impeller linkage? Or???

Thanks.

Without the model number of your Maytag number, I can not determine if when you order a wash pump motor you also get the impeller.
Sounds like you are on the right path to getting your dishwasher to wash dishes again.
Oh, while you have the dishwasher open, check that the heating element has not failed using a Multimeter.

Good Luck!

The seals that the racks "plug" into need replaced. Ours had the same issue and replaced the seals and it works fine now.

Why doesn't upper sray arm work?


  • Improper loading or over loading of dishes and glass ware that blocks the spray arm from rotating; check your user's guide for proper loading methods.
  • the holes in the spray arm can be plugged from food particles or other debris, like coffee grounds; remove the spray arm and clean out the holes; run water through the arm to verify there is no blockage.
  • check to see if the spray arm became disconnected from the feed tube or the feed tube from the water inlet feed hose.; reconnect hose or tighten down on hose clamps
  • check for any filter blockages; remove food particles and debris
  • the tub itself could be under filling, because of a restricted water inlet valve; pour 1 to 2 quarts of water into the tub of the dishwasher and run it; if the performance improves, replace the water inlet valve with a new one; DO NOT try to repair the old valve- it will fail once it's taken apart and put back together.
  • the circulating motor drives a water pump that rotates an impeller, which creates water pressure to go through the washer arms and out the holes. The jetting action of the water pressure exiting the spray arm holes propels the arm to spin...if the water pump impeller is worn, damaged, or impeded by food debris, the cleaning action will be greatly diminished; inspect and clean or replace the impeller if necessary.
  • If the aforementioned trouble shoot and repair methods do not correct the problem, then a more in depth diagnostic check will have to be done by a qualified repair technician to check switches that controls the water/drain pump, (if it is a dual action model for example); to verify if the switch or the pump itself has failed.

Dishwasher will fill and empty but no water coming through the spinners


It would help if you provide the model number.
Usually the problem is with the wash distributor circuit. The water alternates between bottom and top spinners (wash arms). The distributor may be faulty assuming the arms are clean and you have checked this. Some models use the same pump for wash and drain using impeller. In that case the problem could be the impeller is clogged and not allowing water to get in the arms. See this diagram.

Model number will help identify the part.

Water not pumping out


Hello there and welcome to fixya
A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again. Pump Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support. Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them. Drain valve and/or solenoid Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water. Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing. Belt

Bottom draw displaying U1 error message


There is no water coming to the drawer.

This could be due to several reasons. The tap must be on as I presume the top drawer is working.

Could be one or more issues like Inlet solenoid,controller problem, impeller arm not rotating or rotor not sitting properly.

Very poor cleaning all of a sudden


suspect blockage in the actual spray arms - take them out and clean under the tap. a check is to open the door when in operation and see if the spray arms are rotating. they are made to rotate only by the force of water thro angled jets at the end of the arms

Water not getting to the upper level, dishes not cleaned.


Penrod, sounds like a circulation problem. Two things to check first. make sure the upper spray arm is not clogged with debris or split. Second is to twist and remove the filter and clear out any debris where the water enters the circulation pump impeller. If something has jammed the impeller, you would have to remove the dishwasher, remove the tank, remove the circulation motor and clean out the impeller...Catriver...post back.
