Water Temperature  
The wash tank and booster  
tank heaters will begin to heat  
the water in the dishwasher.  
Wait approximately 10 minutes  
for the wash tank water to  
reach operating temperature.  
The temperature should be a minimum  
of 150°F/66°C for (MH-60, MH-6N).  
The MH-6L requires a minimum of  
120°F/49°C. However, a minimum of  
140°F/60°C is optimum for the MH-6L.  
Prescrap the dishes. Load ware into  
the dishrack. Open the doors, insert the

Water Temperature  
Check the final rinse water  
temperature during the  
final rinse cycle.  
The final rinse water  
temperature gauge is located  
in the final rinse piping at  
the top of the dishwasher.  
The final rinse water tempera-  
ture should be a minimum of  
180°F/82°C for (MH-60, MH-6N).  
The optimum final rinse temperature  
for (MH-60, MH-6N) is  
180-195°F/82-91°C.  
The MH-6L requires a minimum final  
rinse temperature of 120°F/49°C.  
However, a minimum final rinse temperature of  
140°F/60°C is optimum for the MH-6L.

Check Final Rinse  
Water Pressure  
The final rinse water pressure gauge  
should indicate a flowing pressure of  
20-22 PSI/138-151.8 kPa during the  
final rinse cycle for all models.  
A pressure reducing valve (PRV) is  
required if flow pressure exceeds  
20-22 PSI/138-151.8 kPa.

OPERATION SUMMARY  
Action  
Result  
1. Push the On/Off power switch “UP” to  
the ON position. Dishwasher fills  
automatically.  
1. The power indicator light illuminates. The  
wash tank heater and the booster tank heater  
begin to heat.  
2. Wait approximately 10 minutes for the  
wash tank heater to heat the water. Then,  
check the reading on the wash water  
temperature gauge.  
2. The wash water temperature gauge should  
indicate a minimum of 150°F/66°C for MH-  
60,MH-6N and 120°F/60°C for MH-6L.  
3. Prescrap and load the ware into the  
dishrack.  
3. Ware should be placed edgewise in the peg  
rack. Cups and bowls should be placed upside  
down in the flat rack. Silverware should be  
spread evenly in a single layer in the flat rack.  
4. Open the doors.  
4. In cycle light illuminates as the dishwasher  
begins a 60 second automatic cycle.  
The cycle times are listed below:  
Insert a dishrack of soiled ware.  
Fully close the doors.  
Opening the doors anytime during the  
automatic cycle stops the dishwasher.  
Closing the doors will resume the cycle  
where it left off.  
Wash = 45 seconds  
Dwell = 1 seconds  
Final rinse = 14 seconds  
5. Check the final rinse temperature gauge  
reading during the 14 second final rinse  
cycle.  
5. The final rinse temperature gauge should  
indicate a minimum of 180°F/82°C for MH-60/  
6N. The optimum final rinse temperature  
range is between 180-195°F/82-90°C for  
MH60/6N. MH-6L optimum is 140°F/60°C.  
6. Check the incoming water pressure  
during the 10 second final rinse cycle.  
6. The water pressure gauge should indicate a  
flowing pressure of 20-22 PSI/138-151.8 kPa.  
A pressure reducing valve (PRV) is required if  
flow pressure exceeds 20-22 PSI/138-151.8 kPa.  
7. The 60 second automatic cycle ends.  
7. The in cycle light goes out.  
8. Open the doors. Remove the clean rack.  
Insert another rack of soiled ware.  
Fully close the doors.

Remove the drain-overflow assembly.  
Clean the scrap screens. Clean the  
dishwasher after each meal period or  
every two hours of operation.  
9. Dishwasher wash tank drains completely.  
Periodic cleaning reduces detergent  
consumption and improves washing results.

CLEANING  
CLEANING  
Cleaning your machine is the best maintenance that you can provide. Components that are not regularly  
flushed and cleaned do not perform well.  
The following schedules are the minimum requirements necessary for the proper performance of your  
machine. Intervals should be shortened whenever your machine is faced with abnormal working conditions,  
hard water, or multiple shift operations.  
CLEANING SCHEDULE  
Every 2 Hours or After Each Meal Period  
1. Drain the dishwasher.  
2. Flush interior with fresh water.  
3. Clean scrap screens and pump intake screen.  
4. Clean spray arm nozzles.  
Every 8 Hours or at the End of the Day  
1. Drain the machine.  
2. Flush interior with fresh water.  
3. Clean scrap screens and pump intake screen.  
4. Clean spray arms.  
5. Thoroughly clean the exterior  
of machine.  
DO NOT HOSE DOWN  
WITH WATER.  
6. Reassemble the machine.  
7. Leave doors open to aid in drying.  
CAUTION:  
Do not leave water in wash  
tank overnight.

CLEANING  
DELIMING  
Your dishwasher should be delimed regularly depending on the mineral content of your water.  
Inspect the machine interior for mineral deposits and use a deliming solution for the best cleaning  
results.  
NOTE:  
Consult your chemical supplier for an appropriate deliming solution.  
WARNING:  
!
Deliming solutions or other acids must not come in contact with household bleach  
(sodium hypochlorite) or any chemicals containing chlorine, iodine, bromine, or fluorine.  
Mixing will cause hazardous gases to form.  
Skin contact with deliming solutions can cause severe irritation and possible  
chemical burns. Consult your chemical supplier for specific safety precautions.  
DELIMING PROCESS  
Model MH-60 and MH-6N  
1. Remove all dishes from machine.  
2. Remove any chemical pick-up tubes from their containers.  
3. Place each tube in a container of fresh water and prime the chemical lines for several minutes  
to thoroughly flush chemical from the lines. Leave pick-up tubes out of their containers.  
4. Drain the machine and refill with fresh water.  
5. Spray interior walls with delimimg solution and let sit for 5 or 10 minutes depending on  
amount of build-up. Add deliming solution to wash tank.  
Do not let chemicals sit for longer than 15 minutes.  
6. Close the doors to run an automatic cycle.  
7. Repeat Steps 4-6 if necessary.  
8. Lift the drain lever assembly and drain the machine.  
9. Refill the machine and run a complete cycle two additional times. Drain and refill the ma-  
chine after each cycle to thoroughly flush any deliming solution from the interior of the  
machine.  
10. Flip the power switch to OFF.  
11. Drain machine.  
12. Deliming is complete.

NOTE:  
DO NOT USE CHASSIS GROUND WHEN PERFORMING VOLTAGE CHECKS.  
Doing so will result in false and inaccurate readings.  
PERFORM VOLTAGE CHECKS BY READING FROM THE HOT SIDE OF THE  
LINE AND NEUTRAL (any #2 or white wire).  
WARNING:  
USE EXTREME CAUTION when performing tests on energized circuits.

WARNING:  
When repairing a circuit, disconnect the power at the main service disconnect switch and  
place a tag at the disconnect switch to indicate that work is being performed on the circuit.  
!
Troubleshooting  
Schematics  
Moyer Diebel places an electrical schematic in the control cabinet of every machine before it is  
shipped. Schematics are included at the back of this manual as well. Be aware that these schemat-  
ics include options that may not apply to your machine. Options are enclosed in dashed lines with  
the words (IF USED) next to them on the schematic. Disregard any options that appear on the  
schematics which are not a part of your machine.  
Tools  
All electrical repairs can be made with: Standard set of hand tools

Refer to Fig. 14.  
There are two fuse blocks, located in the  
main control cabinet. The (A) fuses  
protect the control circuit. The (B) fuses  
protect the wash tank heater circuit.  
Booster heater circuits (MH-60 only)  
are not fused.  
To Replace a fuse:  
Turn the dishwasher main power switch  
off. Disconnect power to the machine at  
the main servicedisconnect switch.

DETERMINE THE CAUSE OF THE OVERLOAD.  
(Three phase shown)  
Motor Overloads —  
The wash pump motor has an overload to protect it from line  
voltage electrical overloads. The overload disconnects  
220VAC power to the motor contactor coil.  
Refer to Fig. 15.  
Switch Lever  
Note the Switch Lever on the Overload.  
If the switch lever is off with the “0” showing  
then the overload has tripped.  
To Reset the Motor Overload:  
Flip the overload switch to the On position.  
A “1” should be visible on the switch lever.  
To Replace a Motor Overload:  
Disconnect the wires to the overload.  
Release the mounting catch on the front  
side of the overload. Push forward and lift out.  
Snap the new overload into place and reconnect  
the wires.

Motor Overload  
To adjust the overload setting:  
The screwdriver in Fig. 15 is positioned
