PROBLEM CAUSE REMEDY
Rinse solenoid is noisy,

coming into tank when output
00 is ON
Particles or other
accumulation has entered
bleed line of solenoid
Low water pressure
Solenoid needs to be cleaned out (see
instruction sheet for fill solenoid)
Make sure filter screen is in place
prior to valve
5-10 PSI water pressure is required to
operate solenoid
No ultrasonics when output 01
is ON. Large cooling fan in
power module is ON.
Fuse blown on circuit boards. Need repair—check that cooling fan is
operating during cleaning.
No ultrasonics when large
cooling fan is OFF when
output 01 is on
Low water level in tank has
activated low level safety
control
Rise solenoid problem, or
insufficient water supply.
In line fuse to PLC is blown.
Relay for fan and circuit
boards not working.
Low-level safety control is
faulty.
As above (fill solenoid problem)
Replace 1.5Amp/120V fuse
Replace relay
Clean deposit off probe
Contact manufacturer
Dryer gets too hot Fan inlet on top off cover is
blocked
Thermostat inside cover needs
adjustment
Dryer Fan not working with
output 06 on
Remove obstacle
Contact manufacturer
Replace in-line fuse to PLC
Dryer is cool with output 03
ON
Thermostat needs adjustment
if there is some heat.
Relay in control module is
faulty
Contact manufacturer
Replace relay
Tank drains with output 02
OFF
Debris lodged in drain
solenoid
Clean out solenoid (see instructions)
and make sure drain screen in place
in tank
Tank does not drain with
output 0N
Drain screen clogged.
