Troubleshooting Replacement Parts
Hood is not cleaning
If the hood does not seem to be adequately cleaned,
look for the following:
Detergent tank — is it empty or filled with wrong
detergent?
Detergent pump — is the detergent pump running?
Is there power to the pump? Is the detergent level
low? If the hood plenum area is not sufficiently
cleaning, consult factory for information on
increasing duration of wash cycle and detergent
pump.
Nozzles — are any of them clogged? If so, they can
be removed and cleared using a small wire.
Water temperature — is it at least 140°F.
Hardness of water — test water for hardness level.
It is recommended that soft water be used.
Hood not draining properly — plugged drain.
Ensure all floats have stamped circles facing up.
Water leaks
— water leaking through the access
panels when filling. Ensure access panels are securely
in place. If leak persists, partially close inlet water ball
valve (by others) upstream of fill solenoid to reduce
water pressure.
Condensation in the hood — large amounts of
condensation while hood is washing. Hood should
be washed after the hood and equipment is warm,
not hot. The warm equipment helps reduce the
condensation that forms in the hood.
