If you have a MAH3000 please look into replacing your bleach and softener dispenser 12002535 wax motors before they fail and trip your circuit breaker. So far, nothing else gets damaged when these particular wax motors fail. Unlike, the R11 and Q6 failure on the machine control board when the door latch wax motor fails.
In addition, if you are experiencing this symptom (breaker tripping) while you wait for your new wax motors to arrive you can disconnect the bleach & softener wax motors so you can at least get some wash done...
I have disassembly photos to help you take your Neptune apart on the above mentioned website.
Until next time...
