How to Fix / Troubleshooting
Safety: Ensure the heater is full of water and there are no leaks before attempting to reset.
- Step 1 – Correct the cause of dr: Resolve any flow, air lock, or low water issues that caused the initial dr error (see dr steps).
- Step 2 – Power reset: Turn off power at the GFCI for at least 10 minutes to allow the control pack to reset. Restore power and check if dY clears.
- Step 3 – Inspect heater: With power off, inspect the heater tube for discoloration, bulging, or burnt smell. If present, replace the heater assembly.
- Step 4 – Monitor operation: After reset, monitor the spa for several heating cycles. If dY returns, have a technician evaluate the Vita Spa control pack and heater for internal damage.
