Bosch SHU5316UC/U12

[Jim B.]

The SHU5316 has died again. This time I diligently searched the site and found the diagnostic proceedure for determining faults.  Ran the diagnostic got a code 4 (fill fault). The machine when you run either the diagnostic or regular run mode sounds like the motor is running but sounds a little strange.

Water is hot and flowing to the inlet valve.

What's my next step?

Thanks!

I do not know Bosch products but would suspect you need to see if you have voltage to the fill valve, if so it is most likely defective, if not need to see where you have lost voltage to the valve..

[Jim B.]

Pegi,

Voltage is .30  Ohms across water valve with leads disconnected is .989

[Pegi]

Voltage and ohms are two different animals....did you check for voltage with your volt meter while the unit was to be filling with water??  Ohms would be checked with power off to the unit and the wires removed from the valve....we want to see if there is voltage to the valve..

[Jim B.]

Those numbers are exactly as you want. Voltage is with unit on, Ohms across poles after valve disconnected from power.

[Pegi]

Like I said I do not know Bosch products but seems to me the valve would need 120 volts for it to operate....we can hope others in here who know these units would help with this thread..

Does the motor run with the door open? If so, you had a water leak and the plastic catch basin underneath the dishwasher is full of water. You need to sop up that water before the machine will fill again.  Check for leaks under there while you are at it.

As Scott said you need to see if there is water in the base of the dishwasher. the uint will not do anything but drain if the flood sensor in the base is tripped. If there is water in the base of the unit you need to sop it out. Then add some type of food coloring to the water after the first fill to find the source of the leak.
