Question about Bosch Dishwashers

1 Answer

Broken plastic gear

Classixx We have owned this dishwasher for many years and it has given very good service The wash water stopped now circulating due to the disc valve inside the water heater not rotating and distributing the water between the top and bottom spray bars as it should I have stripped the unit and found that the engagement splines on the drive cog were worn away Please could you tell me where I can obtain a spare as I am reluctant to throw away the whole machine for the sake of one tiny part I realise that I could buy a replacement heater unit but the cost is over half the cost of a new machine so not economically viable I have a photo of the defective part but I do not know how to attach it to this email richardrowe@dotvet.co.uk

You might be able to mill a workable replacement if the gear isn't overly detailed or fine toothed. Find some uhmw plastic, either buy the sheet or sometimes those nice white cutting boards are made of it. Cut the teeth out with a jig saw. either file out new engagement splines or two part epoxt the new gear back to the drive shaft.

Good luck!

SOURCE: Indecit dishwasher not circulating water

Checked that the motor was not seized by inserting slotted screwdriver through hole at back of machine to engage in slotted end of motor to spin up water circulating motor. Motor was not seized, so that was not the problem. Then took bottom off machine and on inspection found that the start capacitor which is bolted to side of motor was bulging and discoloured wher the terminals are. Replaced Start capacitor ( Less than £10.00) and machine motor started up. Machine behaved irratically at first, flashing lights etc.but got it to reset by switching on and off a couple of times, ran machine through cycle, now working ok.

SOURCE: no water circulation

i had a call on this the other day and the problem was the water valve under the sink was not open all the way. so even though the water valve was energized properly the customer never got the volume the circulation pump needed to wash correctly

Bosch classixx dishwasher not heating water on cooler wash works on hot wash


Most dishwashers don't heat the water. They run on whatever temperature water you have it set for. They have heating coils on the bottom but that's for drying, not heating up the wash water.

Sudden loud vibration from the door of my Whirlpool dishwasher. Replacing the part didn't help.


see this causes and fix it. God bless you
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.

The spray arms on my Asko 1716 dishwasher do not turn - water enters the unit and drains easily, and the heating element also seems to work. The filters and sump are clear, as are the air gap and the holes...


Hello,

Welcome to FixYa.

Based on your description and provided the dishwasher is indeed 1) an Asko D1716 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, do you hear a quiet sound of a motor starting once the unit has completed filling with water ? And be sure the unit is actually filling with water, this image below indicates the normal water level to look for....


macmarkus_284.jpg


The pump obviously it 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.

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 :)

Bosch classixx dishwasher saying check water also not washing or spining


Bosch dishwashers have a food filter to catch food particles. You have to clean it occasionally, or it plugs up and stops water flow. This could be your problem. (Most other makers use a little grinding blade to finely chop the particles so they can be sent down the drain.)

your chicken wish bone may have broken your drain pump- it may have prevented the impeller to spin while the motor was on-not good. you may want to consider changing the drain pump...
