A common issue with a Suburban hot water system installed in a caravan, is that it won't run on gas. Common part numbers for this model are SW6DEA and SW6DA. There are three main causes:
- Gas supply issue
- Electrical issue
- Gas valve issue
- Check your other gas appliances like your stove and fridge and ensure they are running properly. This will isolate the issue to your hot water system, or a common gas fault. You should also check your main regulator to ensure it is putting out the required pressure – normally 2.8kpa (requires a gas pressure meter).
- Check that the hot water service has 12v feed to it for ignition. Most likely cause of no 12v is a blown fuse.
- Gas valve – this is located on the exterior panel of the hot water system, and contains the solenoid that allows gas to flow. These are common failures after a few years use and can require replacing.
