A:AnswerHad that happen before, had to do with the water level getting too low. I cleaned everything week, refilled with no more than the maximum water allowed and it started right up, no problem since. Think it had something to do with re-priming the pump.
A:AnswerAre you using well water? If you are it could have dissolved minerals and perhaps sulphates. We use filtered water (Zero....big cartridges) and we know when to change when the water starts to smell like fish tank water. I would boil some water....and put that in the tank and run it through a few cups and see if that helps.
