WATER FLOWS INTO DRAIN DURING SHUTDOWN
When steamer is shut down and cold water is running continuously into the open drain, either or
both solenoid valves did not close when steamer was turned off.
1. Disassemble solenoid valve(s) and examine for scale or foreign particles lodged in
diaphragm or core tube.
2. Clean valve(s) thoroughly and reassemble, or replace valve(s).
WATER OVERFLOWS INTO COOKING COMPARTMENT
When steamer is first turned on for the day, and the following conditions occur:
- READY light does not come on after about 5 minutes,
- Water begins to overflow into cooking compartment,
- Water fill solenoid valve is open,
Any or all of these symptoms may indicate a problem with the operating probe due to either:
1. A short between the operating probe terminal and body of the steamer. Call your
authorized servicer.
2. Excessive scale build-up on the operating probe. This acts as an “insulation” and prevents
the probe from sensing the water level. It is therefore unable to close the water fill
(solenoid) valve to shut off the water.
As a temporary solution, with power OFF, unscrew probes, check visually, and clean or chip
off scalant. Replace probe.
This problem is an indication of severe harmful water conditions which should be corrected
immediately to avoid damage to the components and ultimate malfunction of the steamer.
