Mark Kent for Model Number Bosch S40T42UK/25 Hi, The dish washer wasn't draining water away. After investigation(google, youtube etc), I managed to find some thread around the impeller, but will probably need to remove the actual drain pump in order to gain better access to check it thoroughly for any more debris. I know how to do this, but how can I check that the drain pump actually works and isn't burnt out for example? I'm thinking of buying a cheap multimeter, but wouldn't know how to check the drain pump is actually working correctly. Many thanks
Answer Mark, once you remove the drain pump, and disconnect the wires, set the meter on the RX1k or 2k scale, place your meter leads across the two terminals, the meter should indicate 14K ohms resistance(+/- 10 %) indicating the motor windings are good. This doesn't really "guarantee" the motor works, just that it should. You may want to use the tech data sheet, program into the test mode and run/operate the drain pump. If you're careful, you can attach a 120 VAC test cord to the motor terminals, plug the test cord into an outlet and see the motor run. Read More...
