Troubleshooting

Problem Possible 

Cause

Remedy

Alternating overheating 

Check connectors and increase size if necessary. If there 

and overcooling or 

are a large number of hoses and/or they are long, try to 

rapid cycling from heat 

Poor water flow

short hose runs and use as large of a hose as possible to 

to cool

minimize water circuit pressure drop. If quick disconnects 
with check valves have been used, remove the check 
valves to reduce pressure drop through water circuit.

Poor connection or failure

Check connection, replace if necessary.

of thermocouple 

Failure of the microprocessor

Replace controller.

Unable to heat properly

Flush out the solenoid valve by adjusting the Set Point up 

Solenoid valve is stuck in

and down several times to open and close the solenoid 

the open position

valve. If this does not work, stop the unit and turn off the 
electric power and water and take the solenoid valve apart
for cleaning or replacement.

Leaking connection and/or

Check for leaks and replace any faulty valves.

the manual pressure relief
valve is in an open condition

Immersion heater is inoperative

Have a qualified electrician check to see if the heater 
and/or heater contactor are functioning correctly and 
replace any defective components.

Microprocessor controller failure

Replace controller..

Failure of thermocouple

Replace thermocouple

Failure of heater

Replace heater..

Failure of heater contactor

Replace heater contactor

Unable to cool properly

Cooling water supply is not

Check to make sure the cooling water supply is of

sufficient

sufficient temperature, volume and pressure for the unit.

Drain (cooling water return line)

Check the drain (cooling water return line) to ensure there

is not sufficient

is no restriction preventing cooling water flow to the drain
(cooling water return line).

Check the drain (cooling water return line) and see if you

Solenoid valve is inoperative

can feel or hear a change in the flow as the solenoid valve
opens and closes. If you can not hear or feel the flow it is 
likely the solenoid valve has failed. Replace solenoid valve
if necessary.

Plugged heat exchanger (only
on models with heat exchanger

Clean or replace heat exchanger.

option)

High backpressure in the cooling

Reduce backpressure. Call our Tech Service Department

water system

for assistance on selecting a pressure-regulating valve.

Heater failure

Unit not filled with water

Fill unit with water.

Faulty heater

Replace heater

Plugged heater tube/flow restriction

Clear obstruction
