cycling on high limit.

 

 

8.

High limit thermostat open.

 

 

9.

Problem with auto blowdown timer (older models).

 

 

10.

Power switch malfunction.

 

 

11.

Pressure reducing valve malfunction or needs cleaned

 

 

 

(direct or regenerated models only).

 

 

12.

Low or no steam supply to steamer (direct or regenerated

 

 

 

models only).

 

 

 

 

 

Steam output low or slow cooking.

1.

Steam gate valve not fully opening or blocked.

 

 

2.

Cycling pressure switch malfunction or needs adjustment.

 

 

3.

Steam header line (supply) blockage.

 

 

4.

Heavy amount of condensate in the pressure controls steam

 

 

 

supply line.

 

 

5.

Pressure relief valve leaking.

 

 

6.

Steam supply lines leaking.

 

 

 

 

 

Boiler leaks water.

1.

Loose water, steam or drain line connections (top or base).

 

 

2.

Boiler hand hole gasket not sealing.

 

 

3.

Leak at gauge glass.

 

 

 

 

 

Boiler fill solenoid cycling to frequently.

1.

LL probe lime scaled over (dry) or damaged and not sensing

 

 

 

water.

 

 

2.

Water level control malfunction.

 

 

 

 

 

Boiler water level too high.

1.

Fill solenoid does not shut off.

 

 

2.

High level probe lime scaled over (dry) or damaged and is

 

 

 

not sensing water (open circuit).

 

 

3.

Water level control malfunction. HL-3 relay not de-energizing

 

 

 

or contacts not opening.

 

 

 

 

 

Boiler does not fill or slow to fill.

1.

Water supply not on or pressure too low.

 

 

2.

Line strainer clogged.

 

 

3.

Fill solenoid not malfunctioning or plugged.

 

 

4.

A High pressure pocket in the supply line to the boiler causes

 

 

 

the fill solenoid valve not to open. See ”BOILER NOT

 

 

 

FILLING WITH WATER” in “SERVICE PROCEDURES AND

 

 

 

ADJUSTMENTS”.

 

 

5.

Water level control malfunction. HL-3 relay not energizing or

 

 

 

contacts not closing to power boiler fill solenoid.
