MAINTENANCE

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY (BOTH DISHWASHER AND BOOSTER IF APPLICABLE) AND PLACE A TAG(S) AT THE DISCONNECT SWITCH(ES) TO INDICATE THE CIRCUIT(S) ARE BEING WORKED ON BEFORE BEGINNING ANY MAINTENANCE PROCEDURE.

Wash Arms

Upper and lower wash and rinse arms (Figs. 14, 15) should turn freely and continue turning for a few seconds after being whirled by hand. To check, DISCONNECT ELECTRICAL POWER SUPPLY (BOTH DISHWASHER AND BOOSTER IF APPLICABLE), rotate arms, and remove any obstructions causing improper operation.

If the slanted strainer or strainer bucket is not properly in place, obstructions (such as food particles or bones) may clog the wash arm nozzles. The wash arms are easily removed for cleaning.

Removing Wash / Rinse Arms — AM14 / AM14C

To remove the lower wash arm, first lift off the rinse arm; then, using a dowel (or end of punch), unscrew the rinse arm bearing pin (Fig. 14) and lift off the lower wash arm. It is not necessary to remove the spacer located on the lower wash arm shaft.

The upper wash and rinse arms are removed by unscrewing the hand knob (Fig. 15) and lowering both arms together. Be careful not to drop these arms.

Motor(s)

The wash pump motor and the blower motor used on gas heat machines are equipped with permanently lubricated bearings and require no lubrication maintenance.

Gas Flue (Machines equipped for gas heat only.)

When cool, check the flue opening every three months for obstructions.
