How to Fix / Troubleshooting
Safety: Turn off power at the breaker.
- Open all valves: In the equipment bay, ensure all slice valves or ball valves around the heater and circulation pump are fully open.
- Bleed air: Loosen heater unions slightly to purge air until water flows steadily, then retighten.
- Clean filters: Remove and clean filters; test with filters out to see if dr clears.
- Check circulation pump: Restore power and verify that the Villeroy & Boch circulation pump runs continuously. If not, it may require replacement.
Persistent dr errors after restoring flow indicate a possible heater or sensor issue that should be checked by a technician.
