Re: bosch dishwasher SGS5312 – stuck on rinse mode
I might have a solution.
Same problem (stuck on rinse) on Neff S4457 built-in dishwasher. At first, quite intermittent, then becoming the norm after a few months. Quality of wash deteriorated over those months, too.
Repair company advised it was the flow meter (impeller jug) but it wasn’t.
There was a blockage in the water labyrinth. The labyrinth is an elaborate collection of water galleries in a fairly flat translucent structure under the left hand panel. Many water connections at the bottom. In this model, there is a vent to the atmosphere at the top. The vent is connected via a complex, tortuous route of small channels to the water galleries. This route was filled with goop which caused a virtual air seal. I assume the blockage had been getting worse over many months. Clearly not a good thing. I removed the labyrinth but it was impossible to access the blockage to dislodge the goop. I tried blowing it out, to no avail. I used a solution of caustic soda (which is hazardous so take care) and a lot of agitation to dissolve the goop and clean the channels.
This is not a solution I have seen offered elsewhere and I suppose it will only apply occasionally. Good luck!
