effect causing a lowering of cooling efficiency. Do not remove

the thermostat, even if the engine tends to overheat.

1. DRAIN ENGINE COOLANT

2. REMOVE AIR CLEANER CAP WITH AIR CLEANER

HOSE

3. DISCONNECT ECT SW1TCH CONNECTORS

4. DISCONNECT ENGINE VIRE PROTECTOR FROM

WATER INLET AND RH CYLINDER HEAD

Remove the 2 nuts, and disconnect the engine wire

protector from the water inlet and cylinder head.

5. DISCONNECT WATER INLET PIPE FROM WATER

INLET AND LH CYLINDER HEAD

a) Remove the bolt and disconnect the inlet pipe from the

water inlet.

b) Remove the O-ring from the inlet pip e.

6. REMOVE WATER INLET AND THERMOSTAT

a) Remove the 3 nuts, water inlet and thermostat.

b) Remove the gasket from the thermostat.

INSPECTION

INSPECT THERMOSTAT

HINT: The thermostat is numbered with the valve opening

temperature.

a) immerse the thermostat in water and gradually heat the

water.

b) Check the valve opening temperature.

Valve opening temperature: 80 - 84CC (176- 183 deg f)

If the valve opening temperature is not as specified,

replace the thermostat.

c) Check the valve lift.

Valve lift: 10.0 mm (0.394 inch) or more at 95CC (203 deg f)

If the valve lift is not as specified, replace the

thermostat.

d) Check that the valve is fully closed when the

thermostat is at low temperatures (below 40CC (104CF)).

if not dosed, replace the thermostat.

INSTALLATION

1. PLACE THERMOSTAT IN WATER PUMP

a) Install a new gasket on to the thermostat.

b) Align the thermostat jiggle valve with the upper stud

bolt and insert the thermostat in the water inlet

housing.

HINT: The jiggle valve maybe set within 15 deg of either

side of the prescribed position.

2. INSTALL WATER INLET

Install the water inlet with the 3 nuts.

Torque: 8.0 Nm (80 kgf-cm, 69 inch lbs.)

3. INSTALL WATER INLET PIPE

a) Install a new O-ring to the water inlet pipe.

were there any thread protectors inside the hot and cold inlets? sometimes they put Styrofoam pieces inside to keep debris out of the inlets and outlets. inspect inside of valve body through inlet holes thoroughly

Hi Michelle,

I hope this is not a duplicate, I am having trouble sending things today and the last message I sent to you is not showing up on my end. If it is a duplicate I am sorry about that.

The inlet protector has a screw near the left side of it that you removed. There is a 'rim' around that screw hole, if you grab that rim with a small pliers and lift from the left side first the cover will come up.

Reply to this if you have questions. I can look for pictures if needed.

Hi Steve,

I am not sure on what you are calling the inlet protector. Check out this link and let me know if it is one of the pieces that are called out here and the number it corresponds to.

This link shows how to clean out the sump so not every part in there is shown.

Check the float(flood) switch inside the dishwasher on the floor of the tub, it floats with the water level shutting off the water inlet valve when water is at the right level to start the cycles.Also check the water inlet valve for good water supply/pressure and clear of any resrictions. Good luck !

Check for a clog in the hose or the dirt inlet by the brush roll. When there is a blockage, the thermo protector will shut the motor off to protect it. That protector could be bad, or a problem with the motor. Is the brush roll turning freely and or is it froze up and won't move.

I had the same problem. Grabbing the little tab and yanking does not seem like the best idea, as it has a groove that fits around the chopper screen, and another lip that fits tightly against the motor housing. There is also a hook at the bottom of the tab that helps hold the cover in place. If you are too rough you could damage stuff. I found if I used a thin lever (screwdriver) on the screw flange side, and worked tthe tab gently with a needlenose, it came free without too much trouble.

Check the inlet down by the brush roll to make sure it isn't clogged. If not and the hose isn't clogged, then probably the thermo protector (part #28382093) maybe bad. It is mounted near the motor. Could be motor Part #43576188. But I would suspect a clog in the inlet or hose, or the thermo protector has gone bad.

Probably not the motor protector, its function is shut off the motor if it overheats. Most likely you have a clog or partial clog in the inlet down by the brush roll, or it is in the hose. But if the motor is running, and suction is low, with no clogs, then maybe the motor is running at a slower speed and will have to be replaced.
