The Pentair Fleck 5800 LXT may continue backwashing until manually turned off due to the following reasons:

1. Incorrect Backwash Time Setting – If the backwash time is set too long, the unit will continue the process until manually stopped.
2. Faulty Control Valve or Programming Issue – A malfunction in the control valve or an error in programming may prevent the system from advancing to the next cycle.
3. Sensor or Timer Malfunction – If the system's timer or sensors fail, it may not detect when to stop backwashing.
4. Power Interruption or System Reset – A power failure or system reset could cause the unit to get stuck in the backwashing cycle.
5. Mechanical Blockage or Valve Sticking – A physical blockage or mechanical failure in the valve could prevent the cycle from completing normally.

Adjusting the backwash time or checking for mechanical or electrical issues may help resolve the problem.

To clean a clogged valve on a Pentair Fleck 5800 LXT, follow these steps:

1. Disassemble the Valve:
- Remove the gearing system as described in the power head disassembly/replacement section.
- Unscrew and remove the piston and top plate.

2. Inspect and Clean Components:
- Remove the brine valve.
- Check for debris or blockages in the piston, seals, spacers, and brine valve.
- Clean the brine valve if necessary.

3. Replace Parts if Needed:
- If cleaning is insufficient, replace the piston and the seals & spacers cartridge.
- Replace or clean the brine valve.

4. Lubricate Seals:
- Apply only P-80® Emulsion lubricant (water-based) to all seals.
- Do not use petroleum-based lubricants, oils, or silicone grease.

5. Reassemble the Valve:
- Reverse the disassembly steps to rebuild the unit.

Following this procedure ensures proper cleaning and maintenance of the valve.
