Question about Bosch 24 in. SHU43 Built-in Dishwasher

1 Answer

Does not wash

Water seems to fill; sounds like motor is trying to work, clicks off, then seems to try again. i know that the drainage impeller is not relevant, but it is clear and drain pump seems to work....i can not find other blockage but maybe looking wrong place. also took out control board and looked for burns under relay...didnt see burns but resoldered critical points anyway

    many thanks for your help; the issue was solved and i believe i posted the solution. Theimpeller could not be turned by hand; however i learned that you could use an 8mm socket on a ratchet to turn it from its hub (from the inside of the washer bottom of tub at impeller; i was able to turn it but not loosen it enough. a tech then suggested filling the basin with roiling boiling water ---that either the loosening of stuff or expansion/contraction might do the trick. Indeed that work. If there is a next time i will try the boiling water and 8mm socket first

Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.

Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.





Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.





Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.





Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.





Circulation and Drain Pump Motor

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the motor sound, it's likely that the circulation and drain pump motor bearings have failed. Once this happens the motor will have to be replaced, the bearings are not repairable.





Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

Washing machine wont complete drainage at end of wash cycle


Look under the washer tub where the drain hose comes out and attaches to the pump. Your pump impeller is either clogged or worn out. Try removing the pump and checking from there.

Hello,

Welcome to FixYa.

Based on your description and provided the dishwasher is indeed 1) an Asko D1776 and 2) filling with water, draining, heating, but not circulating, It sounds like a busted wash impeller within the main motor/circulation pump, as you mentioned. What you may not know, is the impeller itself is not serviceable, the entire motor/pump must be replaced unfortunately.

Before declaring it is indeed a motor/impeller issue, you said you hear a quiet sound of a motor starting once the unit has completed filling with water right ? Be sure the unit is actually filling with water, this image below indicates the normal water level to look for....

The pump will be super quiet if the wash impeller is broke as I suspect it may be...almost like a fountain, since the Asko are very quiet under normal conditions. You will have to either get right down with your ear to the bottom or run it with the door open by activating the door switch with a screw-driver and look for visual/audible clues. (try placing both spray arms at 12 o'clock position and placing a cup upright in the top rack. If the arms move and the cup fills, you've got circulation...if neither, you don't)

If so that is a tell tale of no wash action yet the motor runs, hence broken impeller. If you don't hear anything it may be a wire come off the main motor/circulation pump or severed somewhere between the motor and control, maybe where the door pivots during opening...but not likely.

This unfortunately is common with Asko built dishwasher`s and it is a case of being a victim of their own design.

What happens typically is the ball-bearings from the upper rack holders ( which are plastic, hence fatigues due to heat and fall apart ) come out making their way into the sump, hence breaking the wash impeller from the motor.

Let me know what you find and I'll try and help you move forward from there. If you need direction to remove the circulation motor and pump I can do that, but it is a pretty involved repair and requires pulling the unit from the cabinet. Check those other possibilities first and tell me what you find.

I'll watch for your reply.

Regards,

Macmarkus :)

It sounds like a small rock, dime, or screw may be loose inside the macerator and is rattling around. Can i extract it?


Sounds like you have a broke impeller or the bearings in the motor are bad. Clean it out real good and wash off the impeller and fill with fresh water and try it again allot of times the float will get stuck and the pump will over heat destroying the sealed bearings in the shaft between the pump and impeller this pump uses water to cool the bearings so if it has been dry running you will need to replace the pump.
