    Not to seem too stupid, but how do you put power to the pump? ac/dc? I have no power generation capability except from like a flashlight battery. Do I pull the dishwasher out from the under counter position? I no longer hear the clicking noise that used to occur before the draining began.

It can be the pump or the back-flow valve
The best way is to test it by putting power on the pump and see if it works.
if it rotates it is the back-flow valve

HERE is the drawing and parts list
Make sure it is for the right machine as there are more of that model ( you can enter it in the model section to see for yourself0

Slow or no drain of water. cleaned out sump covers and ran drain cleaner thru cycle. looking for possible secondary filter.


Hi, if the water doesn't drain from your dishwasher, check the drain line and pump..

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.

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.

Hope it helps...

We have a bosch classixx free standing dishwasher and the base is filled with water, we ve removed the filter but there doesn t seem to be anything there causing the blockage.any ideas?


Hello Becky,

The most likely causes are a failed drain pump motor (or capacitor) or a jammed/broken pump impeller. There is a very simply simple test on classixx models which which help you to determine the cause, or where to look next.

1. Turn the wash cycle selector to any wash cycle so the "ON" light is illuminated, but do not press the START/STOP button.
2. Open the door and pull the lower basket out.
3. Locate the 'float', lift it up fully and keep it held up.

(The float is a dome/mushroom shaped protrusion in the base of the washer just to the left of the drain and partially hidden by the spray arm)

When you lift the float, the drain pump should run instantly and the water should drain from the washer. If you can hear a low hum from the pump motor in the base of the washer, but the water doesn't drain, then it's likely that the pump impeller is jammed or it may have broken away from the spindle. If this is the case, try repeatedly lifting and dropping the float fairly rapidly. Repeated stop/start signals to the pump motor can sometimes free a stuck impeller.

If you cannot hear any noise from the base of the washer when you lift the float, then the drain pump motor or the motor capacitor may have failed. A failed capacitor is often accompanied by a buzzing noise. Further testing will be required to determine the exact cause of the fault.

Please try the simple test above and then post back with the results for further assistance.

Hope this helps.

Regards,
BElectric

Water won't drain


Do the diagnostic test:
SHU 53 MODELS

To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ ?21? = version 1 with jumper). When wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button.
To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display alone). Cycle Countdown display will show “88′ when REGULAR WASH button is pressed and “8h” when Delay Start button is pressed.
To start testing, press both the SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended, Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added together, (e.g./ ?6? = faults 2 + 4).
0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault
1 = Aqua Sensor (“Sensotronic”) fault 4 = Filling fault F = Filling fault (display occurs during wash, not test)
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), display will show fault code “4′ and unit will continually fill and drain where testing won’t be completed. If flow switch (e5) has failed (opened), display will show “0′, water won’t heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code “8′ immediately and testing will end shortly after water has started circulating.
---------
The dishwasher not draining is most probably faulty drain pump or drain hose is got bit loose.It has to be checked and confirmed
.You can get required parts from www.repairclinic.com

Water not draining


Set the controls to off then power off at the mains for 30 mins and then power mains back on and run a drain program or a full wash program. If the water won’t drain away then the most likely problems are the door interlock switch is faulty, the drain water motor is faulty, there is a blockage in the drain outlet pipe or filter – this will need unblocking, there is a blockage in the water pump – this will need to be unblocked, the controller board is faulty – but this generally shows an error code. First turn off the mains power to the dishwasher then check the internal filter and screen and clean it thoroughly. Then check the waste water hose and any outlet valve and make sure that it is unblocked and free of any obstruction or waste material. If you have access to the water pump you can check that it is free of obstruction and is able to turn and that none of the impeller vanes have been damaged. Then if all this is OK then try turning on the mains power and running a hot wash cleaning cycle to flush out any remaining sludge / debris.

Wont drain


hello. i can help. unfortunately there are several possible causes for not draining. I will list and explain each one to help you isolate the problem.

If the water doesn't drain from your dishwasher, check these:

Drain line/air gap
Pump
Drain valve and/or solenoid
Belt
Motor
Timer
Drain line/air gap 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 One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.

Motor If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced.

Some dishwashers are susceptible to getting stuck if you don't run them regularly. If you haven't run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can't be serviced.

Timer Part of what the timer does is control the motor and drain valve. If the timer doesn't work properly, the water may not drain and you need to replace the timer. This problem is uncommon.

There is a recall on the control board of many of these models, butyour problem is likely not related. A sticking impeller indicates that the pump may be failing, but you are welcome to try my guide to help. It is here. Thanks!

Bosch SHU33A06/22 does not drain


I think so. Check for power at the pump. If so is it running. There are seperate pumps for drain and wash. It is also possible the impeller came loose and the motor is running but not turning the impeller.
