Siemens Edition 150 dishwasher problems…

[meister]

Siemens Dishwasher (SE58591/06, 1997 model)

Latest status.

The machine made its last wash the other day and it ended with an error code F.

I checked in the left side and noticed that the water regulator switch was not activating when the water level rose, and after that the error code was coming.

Then I removed the water container and the pressure switch and checked by blowing to see if it works. I then put it back together and the machine ran once more without problems.

Now I have the same “F error code”. This happened after the first wash cycle when the machine kept pumping out. It was always like 30 seconds pump, pause, 30 seconds pump, pause etc..

Could it be that the water level regulator valve is detroyed or that it is something else?? 🙁

Hi
F is usually a fill problem.
What I would do is remove front lower plinth and detach clear ribbed hose and clean thoroughly first.

Un plug appliance first before attempting.

Hi Greg,

I’ll take a look at the hose as you say. In fact I checked it from the left side wall (one end so to say) and it looked quite clean.

What I do not understand is when the last error F was displayed, the sump was already pumped out and the waste water pump was hesitatingly pumping, stopping etc…

Is it the water fill regulator switch which controls the waste water pump or some other input device?

Thanks,
Meister.

Hi
If that is clear you could check gunge blockage in the pressure chamber and the top of the water matrix also.

Drain pump is activated by the flood float and also overfill section on the pressure chamber.

Re: Siemens Edition 150 dishwasher problems…

Today I replaced the complete water fill level switch. The unit with the integrated overflow red float and the diaphram pressure switch. I ran a cycle and thought the machine was cured.

Then I watched more closely for the second wash and saw the following on a 55 degree economy cycle…

The cycle is stated as:

1. clean 55 deg.
2. first rinse
3. last rinse 65 deg.
4. dry.

All was going well and then I noticed at the 12 minute mark, the machine drained (the water matrix was empty), then the water matrix slowly filled and after that the machine itself and at the 8 minute mark the error F appeared again. After a minute it turned to 7 and seemed to continue the cycle.

Out of curiosity, I opened the door and the machine was full of water. (I thought it should have been in the drying phase. The last 7 minutes went, the water got pumped out and the display showed 0. I opened the machine and the base of the machine was still wet and rather steamy (which makes sense if it tries to dry whilst full of water).

I really don’t no what next to do. The controller was replaced about 12 months ago and now I don’t know what else I could do…

Any ideas from anyone with similar experience??

Hi
Could be a dicky drain pump, difficult to tell without hands on.
We are getting closer to calling an engineer in TBH as its not a fault readily diagnosed on here 😥

Thanks for the advice Greg,

I have called the Siemens boys out who will come back to me when they have time ;>)

Unfortunately I am so curious that I made some more observations…

I watched the cycle once more and noticed that between the first wash (54 minutes) and the first rinse (44 minutes) 10 minutes elapsed. This was due to the pump out cycle that seemed to pump out the waste water. After the first pump out, more water was let into the sump and the pump started pumping out simultaneously.. This nonsense went on for the full 10 minutes until eventually the sump was full and the next cycle started.

Oh well, I’ll wait anyhow for the Siemens specialists but am anyhow curious about how the pump / fill process works, so if anybody knows, let me know!

Thanks, meister..

This may have been a re-generation cycle where the appliance was flushing out the water softener ❓

Hello NomadPaul

Thats an interesting observation because the last four months I have not been filling up the salt container and have been running with these 3 in 1 tablets. Could it be that this has something to do with the problems?

Worth having a read of this:

Not everything is as it seems…..

Re: Siemens Edition 150 dishwasher problems…

OK, so today I quit the 3 in 1 tabs and filled my old machine up with nearly 2kg salt and rinse aid. It seemed to work much better this time. The regeneration cycle that nomadPaul mentioned was quite quick this time and the cycle continued until the end. No F error codes, no water left in the sump at the end of cycle (that was pumped out in the last 1 minute).

Have I come accross the problem perhaps?
