Water Heater - Not Enough or No Hot Water

We understand the frustration of having not enough hot water or no hot water at all. We are providing some troubleshooting tips for this situation. Hopefully these tips will help you resolve the concern without the need for repair service.

Diagnosing Not Enough or No Hot Water from a Water Heater

If the water heater is not producing enough or any hot water, check the following possible causes and solutions:

Possible Causes	Possible Solutions
Water temperature may be set too low	Increase the water temperature setpoint. If the product has an integrated mixing valve, turn the capacity setting to "High" or "X-High" to increase available hot water capacity.
Cold water inlet temperature may be colder during the winter months	This is normal. The colder inlet water takes longer to heat. Increase the water temperature setpoint. If the product has an integrated mixing valve, increase the hot water capacity.
Leaking or open hot water faucets	Make sure all faucets are closed.
Long runs of exposed pipe, or hot water piping on outside wall	Insulate piping.
Dip tube damaged	Contact your local installer, plumbing contractor, or previously agreed upon service agency.
A fuse is blown, circuit breaker tripped, or electric service to your home may be interrupted	Replace fuse or reset circuit breaker. Contact the local electric utility.
Inadequate wiring	See Installation Instructions.
Manual reset high limit (ECO)	See Safety Controls in Installation Instructions.
Water Connections to water heater reversed	Correct piping connections.
Recirculating System Interference (if installed)	Check flow rate is not set too high. Insulate piping.

Consult the Owner's Manual for the specific model you own for details regarding use and proper installation.
