Hi guys,

Looking for some advice about my dishwasher that has suddenly stopped
heating the water. It seems to operate ok but the water is stone cold
and the tablet is semi-dissolved at the end of the washing cycle.

Does this point to the heating element or are there other possible
reasons for this?

Any help appreciated .

Todd.

The dishwasher should know when the water has heated up and if it
doesn't, e.g. through a faulty heater, then it will usually stop mid
cycle. The fact it carries on regardless points to a thermostat at
fault (common) or programmer fault (uncommon), although I believe it
is controlled from a PCB on this model (from memory) which could be
faulty (mediumly common).

Hi Stuart,

Thanks for the info. I am going to take it apart a bit tonight to
investigate... anything I should look out for ? Is the PCB in the door
(behind the buttons) or located elsewhere?

Usually behind the controls on the door. I haven't got a drawing for
this one so can't tell you exactly where the stat is but I would start
at the stat and heater, check for power and continuity. Hopefully it
will be the stat at fault, as it's the cheapest of the 3
aforementioned parts at 12 quid!

Beware that there will be voltages where and when you don't expect
them inside appliances, excercise extreme caution to prolong your
health!

Hi again Stuart,

Ok, I've had a quick look inside the door panel. I can see a white box
that is the control unit (buttons on the outside) and thats about it
in there. No obvious PCB, although I assume its wrapped up in the
white box.

Do you think the thermostate is likely to be in the door unit
somewhere or could it be in the sides/back of the appliance ? Im
loathed to take it all apart searching.

Thanks agan for your help

Yep, more than likely.

It'll be somewhere under it, or behind it, or on the side, or
somehwere else. I assumed that as you said you were dismantling it you
had some idea what you were looking for. The stat on this, IIRC, is
some large non-thermostat looking device.

It is possible that you might be safer to get someone in to take a
look. As a guide, if it was the stat then from us you'd be looking at
a bill of about 40 odd quid to sort it. I would have replied sooner
but falling asleep in front of the telly took presidence!

Hi Stuart,

Thanks for you reply. I'll call someone out. As you say, it probably
won't be too expensive. Im not massively electrical (Im a games
programmer by trade) but hate the fact that kitchen appliances seem to
be engineered to last just a few years (this dishwasher is just 2years
old).

Usually I just take the item apart and observe. Watch and look for the
fault, then just buy the replacement part. Its worked for my washing
machines 4 times (motor brushes, door latch, condensor unit, mounting
bolds sheared) and my cooker (thermostate blew).... In this case Im
loathed to take it all apart since I don't think I'll see the fault.

Calling engineer now...

Thanks again

Todd

Hi Stuart,

Just to finish off (and maybe get the part required). The engineer
came out and identified it as a failed PCB. It was £159 but he
suggested he repaired it (soldered) as a short term fix allowing me to
buy the part myself. That 'temporary' fix has now failed so Im after
the part. Do you happen to know where I can buy it ? I believe it is
an EDW11 for a ZSF4123.

Thanks for any info.

Have to look into this a bit more tomorrow but basically the EDW11 is
the blank unprogrammed board AFAIAA.

I believe yours is a DIVA/4 which is 93.84 + P&P. If you can give me
all of the numbers off the box the PCB is in (under where it says EDW
11 00 or similar) then I'll confirm that it is the correct part.

Feel free to email me if you prefer, might get a quicker response as I
may miss the odd post on the newsgroup. Replace usenet with stuart in
the email address in the header.
