Common Glow-worm faults
Typical Glow-worm problems include fault codes (such as the F-series on Energy and Ultracom models), low water pressure, ignition lock-outs, and intermittent hot water. A recurring fault should always be properly diagnosed rather than repeatedly reset.

It's rare to find an engineer who is this transparent and knowledgeable. Fair pricing and excellent communication throughout. Will definitely use them again next year and any time we need them.”
