Bosch dishwasher SMV40C30GB/49 FD9901

[dunston]

Hope some can help.
The dishwasher will switch on – will select a program – wash light (brush symbol) and floor LED flashes then after about 10 seconds both lights go out and the tap light flashes. Nothing runs. No water in the base.
Operating the anti flood float the drain pump runs for about 20 seconds.
Guessing something is open circuit, (simpler to a E19 error on different models. This model does not have a dispenser valve)
The customer did say for a couple for weeks he would close the door – it would bleep but not start then he would open the door, press start – close the door and it would start.
Anyone had this problem.

I would check contact, flow through sensor then drain valve

[dunston]

I know the flow thro sensor 00611317 – They usually fail while filling – its not filling.
What’s the drain valve? do you have a part number?

[kaibart]

I had one fail yesterday and it filled and started to wash after a few minutes the check water light came on so start with contact flow through sensor

[dunston]

Its not filling.

you dont say if it pumps at the beginning or not so i assume it does not

so

check pump for blockages
if ok check door sw

Nothing runs at the start. The drain pump will run by operating the anti flood float.
I’ll check the door switch.
I’ve repaired dozens of these dishwashers but the flashing tap light is something I haven’t come across before.

if water light is steady its a fill fault

if its flashing it could be any other fault
