Before you make a service call, first determine if the
problem is:

clock adjustment)
NOTE: The MANUFACTURER IS NOT RESPONSIBLE for
these adjustments.

Power Supply

• Verify that all circuit breakers are reset and working
properly.
• If the temperature display or the Power lamp on the
control panel still does not light, contact the installing
dealer, since it may be a power problem requiring an
electrician.

Description and Solutions
Table D. Control Board Fault Codes — Digital Models
1. Use a pool chemistry test kit to confirm there is no
chlorine in the condensation. Or,
2. Shut the unit OFF and leave the filter pump running
to see if the water stops dripping. If the water stops
dripping, the unit is not leaking.

Water Flow

• Verify that the pool filter is clean to provide good flow.
• Verify that valves are properly positioned to allow
adequate water flow through the unit.
• If the Water Flow lamp (analog models) on the control
panel still does not light, and water is circulating in
the pool, verify that all valves are positioned correctly.

Time Clock Adjustment

Verify that the time clock is set to permit the unit to run long
enough to heat properly.
