TROUBLESHOOTING

ALL MODELS

WARNING: CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TESTS OR MEASUREMENTS WHILE POWER IS APPLIED TO THE MACHINE. EXERCISE EXTREME CAUTION AT ALL TIMES. IF TEST POINTS ARE NOT EASILY ACCESSIBLE, DISCONNECT POWER, ATTACH TEST EQUIPMENT AND REAPPLY POWER TO TEST.

SYMPTOM		POSSIBLE CAUSES
Compartment leaks water around door.	1.	Drain screen clogged.
	2.	Drain line obstructed or not to an open gap drain.
	3.	Steamer not level.
	4.	Excessive cooking compartment pressures.
		A. On models equipped with the compartment pressure
		regulating valve, verify the compartment pressure is 6
		psi during cooking. If pressure is higher then adjust the
		pressure regulating valve and re-check. See
		COMPARTMENT PRESSURE ADJUSTMENT” in
		“SERVICE PROCEDURES AND ADJUSTMENTS”.
		B. On models with out the compartment pressure
		regulating valve, verify the compartment pressure is 6
		psi during cooking. If pressure is higher then adjust the
		cycling pressure switch and re-check. See “CYCLING
		AND HIGH LIMIT PRESSURE SWITCHES (GAS AND
		ELECTRIC MODELS)” in “SERVICE PROCEDURES
		AND ADJUSTMENTS”.
