Re: Siemens SD6 P1S dishwasher
If you are getting E15 code you have water going into the base of the machine and activating the anti-flood switch. Tilting it removes the water from the base, there is a polystyrene float that will then settle again and relieve pressure on the attached switch, clearing the error.
The question is, how is water getting into the base – you must have a leak somewhere. Worth checking that out.
E1 is listed as an electrical issue . . . if you have a leak then water will be finding it’s way where it shouldn’t (in the base tub of the machine) so again you really want to be finding and remedying the leak.
I also have a Siemens, 4 years, it’s been a right pain. Good when it’s working but gone wrong a few times like yours. Wouldn’t buy another, but I think the Zeolith drying system in mine was new at the time and maybe they’ve made it a bit more robust on newer machines.
