Girard GSWH-2 Troubleshooting Guide

If you have encountered an issue with your Girard system and are seeking solutions here, please note there are several common factors related to the hot water service that might be the cause. We recommend following our Consumer Troubleshooting Checklist, as the problem you're experiencing may not be a significant concern.

How does the GSWH-2 detect failures?

The Controller Module will detect failures, and the specific cause will be indicated by an Error Code on the User Control Panel display.
How often should I inspect the GSWH-2 water heater?

Inspect the water heater monthly and have it checked by a authorized technician at least once a year.
What should I check during a routine inspection?

Inspect the seals, ensure air inlet openings are clear, check the Flue Outlet Tube for obstructions, and verify no debris is inside the unit. Regularly inspect the unit's wiring, connections, and combustion areas.
How do I inspect the burner flame?

Inspect the seals, ensure air inlet openings are clear, check the Flue Outlet Tube for obstructions, and verify no debris is inside the unit. Regularly inspect the unit's wiring, connections, and combustion areas.
What should I do if I need service for my GSWH-2 water heater?

What's the Best Caravan Hot Water System?

Girard GSWH2 is distinctively known as the original pioneer of the instantaneous hot water system. Unlike traditional hot water heaters, Girard has invested heavily in creating a quality product that is American designed for superior performance and reliability. This commitment to quality ensures that users can enjoy endless amounts of hot water once they learn how to operate the system properly. Additionally, Girard offers dedicated local Australian phone support, providing personalized assistance to ensure all customer needs are met efficiently.
Power Supply Check

While it may seem basic, please ensure the unit is powered on and confirm there's a stable 12V connection.
Water Supply Check

The RV's cold water system sources its water from a pressurized source, either a shore connection or an RV water pump connected to the RV's fresh water storage tank. This source should maintain a pressure of 45 psi or greater. Please note: A continuous, non-pulsating water flow is essential for consistent temperature and optimal performance.
Gas Supply Check

Ensure there's a sufficient amount of gas in the gas bottle. While your stove may still operate, it doesn't necessarily mean there's enough gas for your hot water service. The hot water service requires 42,000 BTUs, while the stove only needs 12,000 BTUs. *BTU stands for British Thermal Unit. Think of it as the power or "heat strength" of an appliance. A higher BTU means it can produce more heat but requires more gas. It's a way to measure how much energy a gas appliance can provide. You can use a Gas Level Indicator or a Truma Level Check to keep an eye on your LPG levels.
Flow Switch Inlet & Filter Screen Check

Ensure there's no blockage in the Flow switch inlet and the filter screen located externally at the back of the unit. Place a rag underneath the brass fitting at the back of the unit. Unscrew the female tap adapter (see Image 1 for reference). Check and remove any blockages (e.g., dirt, grass) from the filter (refer to Image 2). Notes: Blockages can prevent the sensor from detecting water flow, resulting in the unit not activating or throwing an error code.
Water Pressure Controller/Regulator Check

Ensure there's no blockage in the water pressure controller or regulator. Action: Remove the hose connector and clear any blockages from the filter. Notes: A blockage may cause the water temperature to significantly increase above the set temperature due to inadequate water flow. *The water pressure controller/regulator might resemble the provided image or could be a brass fitting.
Microprocessor Wire Check

Ensure the wires in the microprocessor (white box) are properly connected. Remove the wires and reconnect them. You should hear a 'click' sound when they are securely in place. The blue circles indicate the connections you should examine. Additionally, we recommend conducting a visual inspection of the microprocessor to identify any potential damage.
