Bosch Dishwasher SMS50E22FF 2013 Intermittent fault

[BarnacleBill]

Looking for help with this.
Old machine (10 years old) but used only 2 months a year, this fault has just started.
Refuses to fill and start cycle and both rinse aid and tap closed led’s flashing.
Left unplugged from the mains for a few weeks, reconnected and it works fine for a few cycles
then the same fault returns.

Any advice much appreciated!

Possibly leaking into the base, activating anti-flood. Switching off for a few weeks allows for leakage to evaporate, hence will run again, but only until possible drip leaks enough to re-trigger anti-flood.

Next time it refuses to run, power off, tilt machine back 45° to drain. If it then runs ok, it’s looking more likely it’s the above.

Many thanks for the advice, I’ll look into that!

it will be a leak

remove the lower outer door wrapper

remove the kick strip at the bottom

this will gove you access to a metal cover held on with 2 torx 20 screws.

remove this and look for water in the base

mop this out and the unit shouls run

now run the unit with the covers off but watch with a good torch and look around the base for leaks

Thanks for your reply Dave, however I removed the covers and checked, bone dry no sign of any water.

have you always unplugged this or switched off at the socket between uses ?

Dave

Always left plugged in and switched on at supply.
Before the two lights flash there is a sound of relays on the power unit operating briefly!

one of the problems with a lot of appliances these days is they are not off. your unit has been in standby for 10 years. So even though your not using it the power supply has been on and in use. its possible the power supply capacitors have degraded and are causing your problem

With all modern appliances turn off at the socket, not only to make them last longer but also to stop the small amount of energy they use

At current prices your dishwasher is costing about £12 a year for doing nothing

Thanks for that info Dave, actually it is used in a rental cottage so although on during the summer for around 3 months, it’s off for the rest of the year ie unplugged.
Just wonder if I can remove and open the power module to see if those capacitors are faulty and I can replace them.
I don’t like throwing stuff away if I can fix it.
Thanks again for your advice.

yes you can open it

its on the right side rear. the mains plug is plugged directly in it

Dave

[BarnacleBill]

Here’s the power board and both capacitors test fine….think I will have to give up trying to fix it now!
Thanks for the advice, appreciated!

Sorry, can’t send the photo as it’s too large a file.
