Raypak Protege AGP Pump Troubleshooting Guide
Raypak Protege AGP Pump Troubleshooting Guide
Shut off electrical power and release all pressure before opening the pump or filter system. Never run the pump dry. Start with the simple flow-path checks below before disassembling the pump.
Safety: Disconnect electrical power and follow the manual before opening equipment. Gas, combustion, line-voltage, pressurized-water, and refrigerant work belongs to qualified service personnel.
Symptoms, causes, and actions
| Display or symptom | What it means | Manual-backed check |
|---|---|---|
| Motor does not start | Breaker/switch, fuse or thermal overload, locked shaft, failed winding/start switch, wiring, or low voltage. | Turn the circuit on; replace fuses; have wiring and voltage checked. Replace the pump for a locked shaft, failed windings, or failed start switch. |
| Pump does not reach full speed | Low voltage or connection to the wrong voltage. | Have an electrician verify supply and motor connections. |
| Motor overheats or breaker trips | Low voltage, wrong dual-voltage connection, or inadequate ventilation. | Have voltage checked and relocate the pump if ventilation is inadequate. |
| Pump delivers no water | Not primed, a closed valve, suction air leak, or clogged impeller. | Prime the pump, open valves, correct suction leaks, and clear the impeller if needed. |
| Water leaks at the shaft | The shaft seal needs replacement. | Replace the shaft seal. |
| Low pump capacity | Partly closed valve, plugged or undersized pipe, clogged baskets/filter, or clogged impeller. | Open valves, clear restrictions and baskets, clean the filter, and clear the impeller. Re-plumb undersized lines. |
| High pump pressure | A discharge restriction, undersized return line, or dirty filter. | Open or readjust return fittings, clean the filter, and correct undersized return plumbing. |
| Noisy pump and motor | Clogged basket, worn bearings, suction restriction, plugged/small vacuum hose, or poor support. | Clean restrictions and baskets, adjust the suction valve, verify the base, and replace the pump if bearings are worn. |
| Air bubbles at inlet fittings | Suction-side air leak, dirty strainer-cover gasket, or low pool level. | Repair suction leaks, clean and seat the cover gasket, and refill the pool. |
