Lippert 4 flashes fault code — Water heater
Applies to: Girard GSWH-1
What 4 flashes means
The Lippert Girard GSWH-1 owner manual lists 4 flashes on the diagnostic LED as intentionally NA and reserved for future diagnostics.
Owner-safe checks
- Record the exact LED pattern and whether it repeats after one normal-control restart.
- Treat 4 flashes as a no-owner-repair condition because the owner manual marks it reserved for future diagnostics.
- Contact Lippert/Girard or a qualified technician before further operation if the pattern appears.
Service-only work
- Internal ignition, airflow, flame-sense, gas, blower, wiring, 12V diagnostics, ECO, winter-use-device, and controller work is qualified service work.
Safety boundary
The legacy Girard GSWH-1/GSWH-1M is an LP gas tankless water heater. Shut the heater off for gas odor, overheating, leaks, blocked exhaust, repeated lockout, or repeated LED faults and use Lippert/Girard or qualified RV service.
