Our Siemens dishwasher is seven years old and has worked perfectly until now. We are unable to stop it producing loads of foam at the end on each cycle. We had a Siemens Engineer visit, check it over and offer his thoughts, he could find nothing wrong. We have tried different salt, rinse aid and dishwasher tablets. We have been dealing with this for months now and have eliminated everything. We did suspect a software upgrade to reduce water consumption but have been assured by Siemens that this has not happened. It even produces foam with no tablet or rinse aid in the machine. We're not sure about the Zeolite drying system having any effect. We are reaching the point where we replace the machine out of shear desperation. As a retired engineer this situation makes no sense and seems ridiculous. We have obviously searched the web for suggestions and eliminated all of the causes suggested online.
Any suggestions much appreciated and gratefully received.
Many thanks.
