The E6 error on a hot tub typically indicates a flow or circulation problem. Here's how to troubleshoot and fix it:
Troubleshooting Steps
-
Remove and Clean the Filter: A dirty or clogged filter is a common cause of flow issues. Remove the filter and thoroughly clean it. If it's old or heavily soiled, consider replacing it.
-
Ensure All Jets Are Open: Make sure all the jets in your hot tub are fully open. Closed jets restrict water flow.
-
Reset the Hot Tub: Power cycle the hot tub by turning off the breaker for a few minutes, then turning it back on. This can sometimes clear the error code.
-
Check the Pump: Listen to the pump. Can you hear it running?
- Pump is running but no water flow: This likely indicates an airlock.
- Pump is not running: This could indicate a pump failure. It may need repair or replacement.
-
Address Potential Airlock: If the pump is running but there's no water flow through the jets, try these methods to clear a potential airlock:
- Repeated Resets: Keep power cycling the hot tub as described above (step 3) to try to dislodge the airlock.
- Loosen Fittings: Carefully loosen fittings on the pump (while the pump is OFF) to allow trapped air to escape. Tighten them immediately once water starts to seep out. Be cautious, as water may be hot.
- Bleed Valve (If Equipped): Some hot tubs have a bleed valve on the pump housing. Open this valve to release trapped air. Close it once water flows steadily.
-
Inspect the Plumbing: Check for any kinks, clogs, or obstructions in the plumbing lines that might be restricting water flow.
-
Professional Help: If you've tried all of these steps and the E6 error persists, it's best to consult a qualified hot tub technician. There may be a more complex underlying issue.
Summary: Start with simple fixes like cleaning the filter and resetting the system. If those don't work, investigate potential airlocks or pump problems. If all else fails, contact a professional.
