Symptom

Check

Unit does power on.



Check to make sure power cable is securely inserted into the

receptacle on back of unit



Check to see whether power failure is in progress.



Check whether water/oil level is low.

Circuit breaker (main power switch)
trips.



Check whether unit exterior is wet.



Short-circuit (call for service.)

Er06 appears in display.



Check whether temperature setting is lower than bath

temperature.

Temperature does not come down.



Check whether temperature setting is lower than bath

temperature.

Temperature reading too high/low.



Temperature may not have stabilized yet.



Check to see whether an incorrect calibration offset value

has been entered. (See P.27)



Check to see whether bath temperature sensor has

contaminant buildup, and whether it is properly contacting
bottom surface of bath container.

If problems persist, turn off main power switch immediately, disconnect power cable and call for
service.
