How to Repair a Tankless Water Heater

Depending on the issue, here is the step-by-step guide to repair a tankless water heater.

1. Identify The Issue

Before you begin the process to fix a tankless water heater, you must know what you are dealing with. Identifying the issue is, thus, the first step in the repair process. Here are some of the problems you can face with tankless water heaters.

• No Hot Water—The heater can stop producing hot water after long periods of use. This can happen due to a short power supply or a tripped circuit breaker. 
• Fluctuating Water Temperature – This can happen due to a faulty thermostat or mineral buildup in a defective sensor. 
• Error Codes—The tankless heater can also display error codes. These codes are specific to the heater’s make and model and should be dealt with accordingly. 

2. Safety Precautions

Before you begin the repair process, you should take the necessary precautions. Turn off the power supply to the heater. Shut off the inflow and outflow water supply. Make sure to use proper safety equipment, such as goggles and gloves, before beginning the repair. 

3. Clean The Filters

The next step in the tankless water heater repair is to clean the water filters. Filters can get mineral deposition over time and prevent adequate water flow into or out of the unit. Clean the filters to avoid blockage water and ensure a complete and uninterrupted water supply. 

4. Descale The Heater

Descaling a tankless heater allows you to remove dirt, debris, and grime from the water heater. For this purpose, you will need vinegar and clean water. First, disconnect the inlet and outlet pipes from the heater.

Attach a hose to a bucket filled with vinegar and water. Run the pump and circulate this solution through the water heater for 30 to 60 minutes to clean it. Rinse the water once the cleaning process is done. 

5. Check The Heating Element

If the heater is not giving hot water, you can inspect the heating elements for any signs of water damage. Replace them if they are worn out. We also recommend replacing them if they are not visibly damaged, as the coils can get wear and tear and lead to inadequate heating. 

6. Inspect The Thermostat

Cold water from the pipe can also be caused by a faulty thermostat. Inspect the thermostat to see if it is on and working correctly. Also, inspect the connection between the thermostat and the heater and ensure that it is intact. If the thermostat is faulty, you must replace it with a new one. 

7. Check For Gas Leaks

A good step while doing tankless water heater repairing is checking the gas connection to the heater. You can use soapy water to check the leak. Apply some soapy water to the pipes and the connections of the heater. If you find bubbles forming, gas might be leaking from that area. Tighten the connection or apply other sealing methods if necessary.
