Re: sgs45e08gb/45 bosch dishwasher
Most common cause of this is all of the innards gunged up Cliff. not enough water enters the machine to trip the flow meter microswitch in the heater box.
Take off the left hand (from front ) side and the plinth and check the transfer pipe that you can see bottom left at the front and the float chamber/pressure switch assembly at the side.
If the very top, left hand corner of the large plastic fill matrix has signs of dark sludge then that will also cause the problem, that one is very difficult to clean and a new chamber is the best option.
You can megger the element from the other side.
If you enter “Bosch AND one AND minute” into the search facility in that exact format but without the quotes you will get plenty of reading.
