Common Girard GSWH 2 Tankless Water Heater Problems
Here are some common issues you might encounter with your Girard GSWH 2 tankless water heater:
1. No Hot Water
This is the most common problem with any water heater, and it can have various causes.
- Low Water Pressure: The Girard GSWH 2 requires a minimum water pressure of 30 psi to operate properly. If the pressure is too low, the unit may not be able to ignite or produce hot water.
- Faulty Ignition System: The ignition system is responsible for igniting the gas burner. If this system malfunctions, the unit won't start. This could be due to a faulty igniter, a clogged gas line, or a problem with the control board.
- Blocked Water Inlet: If the water inlet is blocked, the unit won't have enough water flow to operate correctly. Check for debris or sediment buildup at the inlet.
- Insufficient Gas Supply: The unit requires an adequate supply of natural gas or propane to function. Verify that the gas valve is open and there's sufficient pressure to the heater.
- Frozen Water Pipes: In cold climates, water pipes can freeze, preventing water flow to the heater.
Troubleshooting Steps:
- Check the Water Pressure: Use a pressure gauge to measure the water pressure at the heater's inlet. If it's below 30 psi, you'll need to increase it.
- Check the Gas Supply: Verify that the gas valve is open and that the gas line is unobstructed.
- Check the Water Inlet: Ensure the water inlet is clear of any obstructions or debris.
- Reset the Unit: If the unit has a reset button, press it.
- Check the Ignition System: If you're comfortable working with electrical components, you can check the igniter for continuity. If it's faulty, you'll need to replace it.
2. Erratic Hot Water Temperature
If your hot water temperature fluctuates or is inconsistent, there could be a few reasons:
- Low Water Pressure: Insufficient water pressure can affect the water flow rate and, consequently, the hot water temperature.
- Dirty Water Filters: The water filters in the Girard GSWH 2 can become clogged with sediment over time.
- Malfunctioning Temperature Sensor: The temperature sensor monitors the water temperature and sends signals to the control board. If it's faulty, the unit may not be able to maintain a consistent temperature.
- High Demand: The tankless water heater may not be able to keep up with a high demand for hot water, particularly if multiple appliances are using hot water simultaneously.
Troubleshooting Steps:
- Check the Water Pressure: Ensure the water pressure is within the recommended range.
- Clean the Water Filters: Consult your owner's manual for instructions on cleaning the water filters.
- Check the Temperature Sensor: If you're comfortable working with electrical components, you can test the temperature sensor for continuity.
- Adjust the Temperature Settings: Adjust the temperature settings on the control panel if necessary.
- Reduce Hot Water Demand: If multiple appliances are using hot water, try using them at different times to reduce demand.
3. Water Heater Making Noises
A noisy tankless water heater can be an annoyance, but it's important to address the problem promptly.
- Water Flow Issues: Insufficient water flow can cause the heater to make a gurgling or rattling sound.
- Sediment Buildup: Sediment can accumulate in the heater, leading to rattling or knocking noises.
- Faulty Vent System: A blocked or damaged vent system can create unusual sounds.
- Gas Line Issues: Leaks or problems with the gas line can cause a whistling or hissing sound.
Troubleshooting Steps:
- Check the Water Flow: Make sure the water flow rate is adequate.
- Flush the Heater: Consult your owner's manual for instructions on flushing the heater to remove sediment.
- Check the Vent System: Inspect the vent system for blockages or damage.
- Check the Gas Line: If you smell gas, turn off the gas supply and call a qualified technician immediately.
4. Water Heater Not Igniting
If your Girard GSWH 2 is not igniting, it could be due to one of several factors.
- Low Gas Pressure: Insufficient gas pressure may prevent the unit from igniting.
- Faulty Ignition System: A problem with the ignition system, such as a faulty igniter or a clogged gas line, can also cause the unit to fail to ignite.
- Control Board Issues: The control board is responsible for regulating the operation of the heater. If it malfunctions, the unit won't ignite.
- Gas Valve Problems: The gas valve may be stuck in the closed position, preventing gas flow to the heater.
Troubleshooting Steps:
- Check the Gas Pressure: Verify that the gas pressure is sufficient.
- Check the Ignition System: Inspect the igniter and the gas line for blockages or damage.
- Check the Control Board: If you're comfortable working with electrical components, you can check the control board for continuity.
- Check the Gas Valve: Ensure the gas valve is open and operating properly.
5. Error Codes
The Girard GSWH 2 tankless water heater features an LCD display that can show error codes indicating various problems.
- E1: This code indicates a problem with the gas flow. Check the gas valve and ensure the gas line is not blocked.
- E2: This code signals a problem with the water flow. Check the water inlet for obstructions and ensure the water pressure is adequate.
- E3: This code indicates a problem with the temperature sensor.
- E4: This code signifies a problem with the control board.
