Guessing the replacement didn't go as planned. recheck the wiring for wrong or loose connection

SOURCE: E.E.C fuse keeps blowing in 1991 Ford Explorer

if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing

sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

SOURCE: horn fuse keeps blowing out

Check the wiring around the horn and make sure nothing is touching metal...look under the hood at the horn and make sure everything is pluged in and there is no water on any plugs or wiring...Make sure the fuse is the correct number (ex: 10, 20, 25) If it is still blowing out the fuse then you after you do some checking then it is a short in some wires

SOURCE: fuse for instrument & tail lights keep blowing

if its blowing fuses, you have a short(power being touched to ground) Electrical can be hard to trace. Find you a wiring schematic for you vehical and trace each wire, look for loose connections and possible wires melted to each other. Hope this is a help.

We had the same problem but when we put in a new fuse it smoked. It turned out to be something with the master cylinder and required the changing of a 20 dollar part by the mechanic and problem solved

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.

There are one or two hi-limit relays on the booster. One is on the front and if there is a second one, it is on the right hand side as you face the front of the unit. They are both manully have to be reset if tripped. Check them and also the booster's contacter

Lx30h hobart dw. booster will not turn on. element good,hi-limit is good, changed temp probe, still no power to contactor


The booster heat control circuit is controlled by the relay board. Visually check for loose or burnt relay contacts...
You will see the booster LED light when it calls for heat. Some newer machines have a second high limit on the right hand side of the booster tank.
It may be your control board is configured for low temp with no booster. When you power up, the display should say LX30H. If not
Pull open the upper drawer, place a magnet over the door interlock switch.

CAUTION, 220 volt power is present. be carefull what you touch.

on control board, short J5-1 and J5-2, then power up. You are in factory setup. press select on the control board to see each option on the front panel., press up arrow on control board to step up through options for each step. when done, press the off button on front panel. remove short and start up normally. With the magnet in place, AND THE DOOR CLOSED, run the machine and observe the relay board status lights.
If you want to adjust the temp set points, with the machine off, press and hold the hidden key behind the front panel logo, and press select on the control board.. Or on power up, hold the wask key..Same to adjust options as above. Press off to exit.

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!

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.
