BEFORE YOU CALL SERVICE

Troubleshooting Tips: Save time & money! Review the chart below first 

&

 you may not need to call for service.

Elapsed Time 

 Possible Causes 

 What to Do

Water heater is noisy

Water heater is making 

the room too cold

Water dripping down the 

outside of the heater

Not enough or no hot 

water

Water is too hot

Rumbling noise

Fans  are  used  to  move  air 

through  the  system.  The  fan 

noise  volume  will  vary  as  the 

water is heated

.

Condensate drain hoses are not 

connected.

Water usage may have exceeded 

the capacity of the water heater.
A fuse is blown or a circuit breaker 

tripped.

Electric supply may be off.

Water temperature may be set too 

low.
Leaking or open hot water faucets.

Electric service to your home may 

be interrupted.

Improper wiring.
Manual reset limit (TCO).

Cold water inlet 

temperature may be colder 

during the winter months.

Water temperature is set too high.
Electronic control has failed.
Water conditions in your home 

caused a buildup of scale or miner-

al deposits on the heating elements.

Condensate drain hoses are 

Kinked or clogged.

Room is not vented property or 

is too small

.

• Some amount of fan noise is normal (similar

to the blower on a central heating and cool-

ing system). If you hear an abnormal noise like

a knocking of the noise level seems unusually

loud, then contact service.
•

If noise level has been increasing over

several weeks or months, the filter may be

getting dirty, thus making the fans work

harder. Check to see if filter needs to be

cleaned. (See page 13 for instructions).

• Two drain hoses are included with your wa-

ter heater. Connect the longer 6” hose to the

lower condensate drain port. Connect the

short 3” hose to the upper condensate drain

port.

• Wait for the water heater to recover after

an abnormal demand.

• Make sure electric supply to water heater

and disconnect switch, if used, are in the ON

position.

• Replace fuse or reset circuit breaker.

• See the water temperature setting section.

• Make sure all faucets are closed.

• Contact the local electric utility.

• See the installation instructions sections.
• See the water temperature setting section.
• This is normal. The colder inlet water takes

longer to heat.

• See the water temperature setting section.
• Call for service.
• Remove and clean the heating elements.

• Remove each drain hose and clear any debris

from the line. You can use a small wire like a

hanger or a small screwdriver to clear out any

debris in the drain port on the unit.

• If  the  room  is  smaller  than  10’  x  10’  x  7’, 

then it must have a louvered door or other

means to allow air exchange with surrounding

rooms.

CAUTION:

 

For your safety, DO NOT attempt to repair electrical wiring, controls, 

heating elements or other safety devices. Refer repairs to

 a

 qualified service professional.
