Dishwasher Problems - Water will not drain out

Hi,

Welcome to FixYa.

Based on your description and provided the dishwasher is indeed 1) an Asko 1885 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.

First though, do you hear a quiet sound of a motor starting once the unit has completed filling with water ?

( 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...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...you may opt to call in a pro. I'll watch for your reply.
Regards,

Macmarkus :)

Hi.

The impeller pump is probably faulty.

Before going for the pump check the drain well and drain hose, drain blockage may prevent the machine from switching to recirculate. Also double check there is no blockage or leak in lines to spray arms and that the orifices are not clogged.
Testing on the impeller is done energizing the pump to check if it switches to recirculate and accessing pump hose checking for blockage.

Other parts that must be tested are the door switch, that can interrupt the cycle, and the thermostat, that is used to determine when to start the impeller pump.

If pump and all the part mentioned above are OK, then the problem is a defective control module.

Hi,
The only way to pinpoint the problem will be to use a electrical meter and check to see if there is power going to the motor or not...if there is power then the motor quit... no power and a relay in the board is bad... and the board needs to be replaced...
