The most common reasons for a pool pump circuit breaker to trip are an overloaded motor, underrated pump breaker, bad motor windings or other earthing issue, moisture in the motor or moisture in the wiring.
Thereof, why does my pool pump keep tripping the GFCI breaker?
-If the issue occurs when it rains or after sprinkler use – It is likely that moisture has accumulated on the wiring connections or the motor windings. This will cause a small fault to the ground that will trip a GFCI breaker. Check the area around your pool pump.
Herein, should pool pump run continuously?
Although it’s generally recommended that all the pool water undergo filtration every 24 hours, the pump does not need to run all the time. A proactive, productive and energy-saving maintenance activity is to remove the debris floating on the pool surface with a hand-held skimmer.
How do I reset my pool breaker?
It could be a bad drive, over voltage, under voltage, drive over heating, ect. You could eliminate it being a control problem by unplugging the control cable on the motor, and manually running it. If it does not do it anymore then it is a control issue.
You can run a piece of bond wire to the metal current during parts to pick up the GFCI protection. The pool pump however this is not necessary because they usually come together in pieces. Only GFCI protection on the motor itself is really required.
Overheating. For safety reasons, many pool pumps are designed to shut off automatically if they begin to overheat. The mechanisms that perform this task are known as thermal overload switches. If your pump continues to shut off, it could mean that the thermal overload switches are going bad.
When a pool pump gets too hot (or too old), the grease insulation fails and the current begins to find new, shorter pathways to travel through the windings. Instead of flowing down the length of the wires in the windings, the current begins to short circuit.
A tripping circuit breaker usually means that the current being drawn on the circuit is too high. In the case of a water pump that may mean that the pump motor itself is failing. For example a bad bearing can cause the pump to draw more current as it tries to turn.
A GFCI breaker or outlet typically lasts for 15 years, depending on the use. You should check it once a month and search for bad GFCI symptoms and change it every decade. Overloading is highly problematic, for you may experience an early failure and overheating that can melt plastic.
A Quick Fix
One quick thing to check is if the “reset” button on the GFCI simply needs to be pressed back in. If the GFCI trips, then you will need to press the reset button to restore electricity back to your equipment.
