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 15 minutes,
- Water begins to overflow into cooking compartment,
- Water fill solenoid valve is open,
then 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. (See WATER CONDITIONING in this manual).
HEATER ELEMENTS DO NOT COME ON
When the steamer is turned ON and heater elements do not activate, and therefore, the
READY light does not come on, then the contactors may be burned out. If a
considerable amount of “chattering” of contactors has been previously experienced, then
the thermostat bulb may be coated with scalant and unable to sense water temperature
in the boiler accurately, and therefore unable to control the contactors.
1. Replace contactors.
2. Unscrew operating thermostat bulb, clean off scalants and screw thermostat bulb
back in.
This problem is an indication of inadequate water quality and is not covered under the
warranty. Have water quality analyzed and corrected immediately to avoid complete
malfunction of the steamer.
