Pump loud, will not prime or will not start.

A pool service technician should work on the pump, and a licensed electrician should take any supply or wiring fault.

Customers put it like this

  • pump won't prime
  • basket is half empty
  • pump got really loud
  • motor hums but won't start

Stop first if

  • Water reaches the pump, motor or any powered equipment.Stay out of the water. Shut off power only if it can be done without risk. Call a licensed electrician.
  • A pump ran dry or would not prime.Do not open the pot until it is cool to the touch. Leave it for a technician.
  • Someone wants to open or tighten a lid or clamp while the system holds pressure.Stop. Nobody touches it until a technician has relieved the pressure.

Ask on the call

Homeowner? These are the questions a good technician will ask you. Having the answers ready makes the first visit count.

  1. Is the water about halfway up the skimmer opening?
  2. Is the pump above or below the pool water level?
  3. Does it lose prime after every shutdown, or while running?
  4. Are there bubbles at the returns or in the pump basket?
  5. Does the pump display show an alarm?
  6. Where is water dripping from, if anywhere?

  1. Identify the pump type and its inlet height against the water level.
  2. Read the drive display and event log with the pump running.
  3. Check water level and both baskets, and look for bubbles at the returns.
  4. Read suction vacuum at the strainer and record it with the pump speed.
  5. Have a qualified person measure voltage at the pump under load.
  6. With power locked out and pressure relieved, a technician turns the shaft and inspects the impeller.
