Boiler issue resulted in E12 error on Siemens Washer Dryer

Hi, I wonder if someone can help. I had a problem with my boiler this week. Pump, pressure valve and PCB were replaced - FYI

My Siemens washer dryer is showing error code E12 and not going a few minutes into the cycle with a but of water going into the drum, does any one think the two are related? Seems a coincidence that a day after the boiler is repairs the Washer dryer is not working? 

Have been onto the siemens site and consulted the manual and no mention of E12 error and any diy resolve. So any help/pointers greatly received. 

Thanks

Have you switched the power off, unplugged and waited a few mins before switching back on?

The only way I can see the boiler issue being linked is if there had been a power surge that's affected both appliances e.g. damaged the circuits.

Thanks NSG666 - yes, left if off overnight - same thing in the morning, dreaded E12.

Washer Dryer was working while i was waiting for boiler to be repaired but interesting and thought provoking diagnosis...

Bosch, Neff and  Siemens seem to have a lot in common.

The e12 error code in Bosch washer means that the time of waiting for water to enter the washer has been exceeded. Various Bosch washer models have a different response time and errors displaying. Anyway, as a rule, it is up to 5-6 minutes.

I think the inlet valve is blocked - very likely especially if it has a mesh filter.

Good shout from Grumbler. There is often a mesh filter in the connection between the filling hose and the appliance valve. Turn off the valve and remove the hose to look - shouldn't need tools.
Also, and beforehand, just have a look along the pipe that leads to the appliance valve - is there a valve or stop tap that the guys repairing the boiler might have turned off when trying to find your stop tap? That would certainly tie in with the fact that it worked ok right up to the boiler being worked on.

All brands of Bosch Siemens Hausgerate (along with Gaggenau). Very often the same or similar machines under different skins & at different prices ...

Had this yesterday, it was a blocked filter. Open it up with a bowl in front to catch the water and give it a clean out.
