Girard Water Heater: “En / End”
info RV water heater fault codes
What it means
Not a fault. This is the system timer: the board ends the burn after 20 minutes of continuous operation and displays this code on the user control panel. A tankless heater that runs perfectly for twenty minutes and then stops mid-shower is doing exactly what it was designed to do.
Most likely causes
- Hot water drawn continuously for more than 20 minutes most likely
- A hot tap or an outside shower left running unnoticed common
- A leak or a mixing valve passing water continuously, keeping the heater firing less common
Safe checks you can do yourself
- Check whether the burn really did run 20 minutes without a break — an outside shower or a dripping hot tap keeps the flow sensor active.
- If the timer trips far sooner than 20 minutes of actual use, something is holding flow on: look for a passing mixing valve or a hot-side leak.
How to reset / clear En / End
- Soft reset: turn the hot water tap off and then back on. The heater resumes.
- No power cycle and no service action is needed.
When to call a technician
The timer trips repeatedly after only a few minutes of real use, which points at unintended continuous flow rather than at the timer.
Accuracy notes
Girard's own manual is inconsistent about how this appears on the panel: the troubleshooting section says the board shows "En", while the code list at the back of the same document calls it "End". Both refer to the same 20-minute system timer. It is listed here under both spellings because owners search for what they actually see.
