SOURCE: Continuous beep after power went off and on

I'm the one who posted on May 23. I tried turning off the breakers and it was still beeped when powered back on. I ordered a new touchpad and control module. When I replaced the touchpad, the beeping was gone, but not all the buttons worked, so I changed out the control module, too, and it works:) I'm going to put clear caulk along the top to prevent spills from leaking through the front panel.

SOURCE: Thermal fuse keeps blowing

Mr. Larry (guru?)
The thermal fuse is just that It doesn't protect the circuit from over current although it certainly can open in that case. It is there to protect the board from overheating , thus the term thermal. The dishwasher could be allowing the water to heat too hot or the water heater in the home is turned up too much. The heater could also be shorted to case thus allowing it to be on even though the control is not calling for it especially if the polarity is incorrect to the dishwasher or the relay on the board could be welded closed so that the heater can't turn off even though the thermostat is satisfied. The best thing is to get a person who can check these things. You don't necessarily need to change the board with a fuse. I have changed many fuses with no other problems and verified that the machine was still working years later. sometimes the fuse just blows!

SOURCE: HOBART FX-20 dishwasher out of order

There is one glued to the lower panel on the inside. Hobart is very tight lip'd when it comes to getting any info from their web site. Best I can do, sorry.

SOURCE: Hotpoint dishwasher BF1620 blew the main fuse

This is happening because you have a very bad fault, a Phase to Earth short, problem. Leave machine UNPLUGGED, Breaker/Fuses OUT. do NOT use it, nor Touch it, It is possible to get severe electric shock. PLEASE get a registered serviceman to inspect this unit.

I have a Whirlpool ADP9000ix diswasher that will not power the front display/touch panel. Therefore cannot turn the dishwasher on. I have checked the circuit control panel. And power is getting to it....


If your Whirlpools over there are like the older ones here in the U.S., you may find that there is a thermal fuse mounted just above the circuit board. If there is one, turn off the power to the unit, pull off the 2 wires connected to it and check it for continuity with a multimeter. If that fuse is blown, nothing works as it controls all power to the unit. Replacement fuse kits (at least here in the U.S.) are readily available on ebay for a fraction of the price that an appliance parts store would want. By looking on ebay for "Whirlpool dishwasher fuse" you can see what the fuse assembly looks like, and if identical to yours, purchase one. If you do buy one, follow the installation instructions exactly by using the supplied wires on the new fuse and the screw terminal block to make the connections. If you don't use the new wiring and connection block and simply plug the new fuse to the old connectors, it will simply blow again in a short time.

Hobart LX30H no sump or booster heat


Check the heat circuit of your dishwasher. This will include your control, heat element, thermostat/thermal fuse, & sometimes your door switch. Check your thermostat/thermal fuse and heat element for continuity first. If all test good, go to your control and possibly your door switch. Check for voltage from your control and continuity of your door switch.Use the VOM. God bless you

Hobart H600 Double Pole Breaker


You need to get a new electrician; a real electrician would read the power requirements on the motor name plate and install the correct voltage and amperage circuit.

A single pole breaker does not supply the same voltage as a double pole breaker. It hums because the voltage is wrong

This dishwasher is older than most living people in this business. It works great except it is a 208 three phase unit. It is in St.Peter's church in New York Mills, MN. We bought it used during our remodel...


Your AM9 is too old to get new parts from Hobart.
Why does the inverter need to run when the machine is not in use? There must be a breaker to turn it off.
If you decide to replace it, any AM series will fit your tables. Don't buy anything older than AM14.

Commercial Hobart dishwasher


I can't imagine a bad relay board would blow a fuse. The relay board would need to make a bad connection to ground to blow a fuse -- I don't see it.

If you could supply me with the ML#, I'll take a look at the wiring diagram and give you an educated answer.

Not that I recall clearly which fuse is for the drain solenoid, but the two sound related. If a drain valve is obstructed by debris, it will heat up the coil and short it out. I don't know the spec'd ohms, but I would suspect at least 50. I'd check it.
