Troubleshooting
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.
