Hi, My brilliant Siemans integrated dishwasher was installed

This answer was rated:

My brilliant Siemans integrated dishwasher was installed in 1996. Its never failed me until today. Its stopped its cycle with 15 mins to run - the bottom is full with dirty water and there are a several warning lights on the dashboard which have not been lit before - one looks like a tap, one like an 's' with an arrow at each end and one like a snowflake. All are lit red.
Only other info I have is I noticed the filter was badly clogged a few days back and I cleaned it thoroughly.
Any ideas on where I might start please?
Can you post the E-Nr number of the appliance please?
If it's not on a label it will be very faintly etched across the top of the inner door.

Its SE64M359GB/01

Thanks for that.

This can be caused by several things but, the most common is a blockage in the drain pump.

Manually remove the water inside the machine.
Take out the filters and remove the water in the sump bowl.

Once empty, look into the sump bowl and on the left you'll see a cover held by a single Torx screw.
Take the screw out and take the cover off.

Remove any debris jamming the pump impellor.
Turn it manually to ensure it can turn.

Refit the cover, ensure it's fitted properly.
Refit the Torx screw.

Now try the machine again.
If there are no further faults, it should drain and work again.

Get back to me if there are problems,

Hope this helps

Thank you for that. I did suspect a blockage but am not going to be able to do as you suggest until much later tonight as I now have to get back to work.

I will leave this page open and reply after I've done what you suggest

One question though - what is a torx screw?

Thanks again

No problem.

Torx screw is the type with a multi starred head on it.

You need Torx screwdrivers or Torx bits to get them out.
They are a form of security screw.

You can get drivers and bits from Halfords, B&Q and some Pound shops.

Hi again, sorry for the delay but I didn't get a chance to try your suggestion until just now.

I manually drained the sump, and removed all covers to the pump as you suggested. The pump impeller was ok but the drain holes into it were quite blocked. I cleaned everything, reassembled and ran a cycle and all is pumping again though it does not seem to be heating the water (certainly as it previously did) - could this be a related problem?

I'm afraid I'm away from the machine again for a couple of hours but if you've any suggestions I will be able to check/implement later this afternoon.

Not heating would be a different fault.

You'll need to unplug the appliance.
take it out and take the top (if it's not an integrated machine) off.
Take the left side panel off.

Look at the tanks there, are they blocking up?

Customer: replied 4 years ago.

Thats fine - will take me some time though.

Would it be typical for a hot tank to block up if the sump had been blocked and had a lot of crap in it? Just seems quite coincidental.

Or - could it be that the sump is draining more efficiently now and the warm water is being removed quicker so it doesn't seem as hot?

It's not a hot tank, it's the food stuff that's built up and gone past the filters, it's likely blocking up the transfer hose and the pressure chamber.

We'll know when you take off the side panel.
If the chambers are dirty, it's food stuff blocking it up.

If it doesn't fill properly, which happens when there's blockages, it doesn't heat.

managed to get off work early and home - have side panel off.

Theres a big slim plastic see through tank at the back left. Its got what looks like some dirt in it at top/back. Its connected to various hoses at the bottom.

Is there any easy way to clear it or do I need to disassemble all hoses etc

Look at the smaller tank nearer the front.
Is it beginning to block?

Customer: replied 4 years ago.

i have it running with the panel off,

Theres a set of three small tanks front bottom - front one has some kind of float switch with a red lever. both look a little dirty but not too bad. hard to tell really . anything i can watch for while running that will tell me more

You need to take the large tank off.
Then the pressure chamber (the one with the float in it) off.
Take it apart and clean it out thoroughly.

There's a hose attached to the front of it.
Take the panel below the door off.
Take the hose off and clean it out.

Reassemble and try again.

Customer: replied 4 years ago.

ok I'm happy with that.

I ran it empty a couple of times and it seems pretty good now.

Is there any cleaning solution I can run thru it which would help?


How do I sign off as happy with your service

You just need to rate the answer I provided and it complete the question and answer dialogue.

If you have problems with the water not heating, this is the most common cause, blocking up the transfer hose and pressure chamber leads to the machine under filling, this in turn doesn't activate the switch on the heater.

Good luck with the appliance.
