DIY Troubleshooting Tips

1. Check the Power Source

The first thing to check when your tankless water heater isn't working is the power source. Make sure the unit is plugged in and that the circuit breaker hasn't tripped. If the power source is fine, move on to the next step.

2. Check the Water Supply

If your tankless water heater isn't producing hot water, the issue may be with the water supply. Check the water shut-off valve to make sure it's open and that there are no leaks in the pipes. If the water supply is fine, move on to the next step.

3. Check the Gas Supply

If your tankless water heater is powered by gas, check the gas supply. Make sure the gas valve is open and that there are no leaks in the gas line. If the gas supply is fine, move on to the next step.

4. Check the Venting

If your tankless water heater is producing an error code, it may be due to a venting issue. Check the venting system to make sure it's clear of debris and that there are no obstructions. If the venting is fine, move on to the next step.

5. Check the Water Filter

If your tankless water heater is producing an error code or isn't producing hot water, it may be due to a clogged water filter. Check the water filter and clean or replace it if necessary.
