PROBLEM
CAUSE
REMEDY
Rinse solenoid is noisy, pulsating and little or no
water 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.
As above (fill solenoid problem)
Replace 1.5Amp/120V fuse
Replace relay
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 02 0N
Drain screen clogged.
Y strainer clogged
Solenoid not operating
Clean and replace screen.
Clean out Y strainer
In-line fuse to PLC is blown or clean out solenoid valve
