The “thermal overload protector” will allow the motor to automatically restart once the motor has cooled. It will continue to cut On/Off until the problem is corrected. Be sure to correct cause of overheating. Motor Hums, But Does NOT Start – Check For: 1. Impeller jammed with debris. Solution: Have a qualified repair professional open the pump and remove the debris. Pump Won't Prime, Check For: 1. Empty pump/strainer housing. Solution: Make sure pump/strainer housing is filled with water and cover o-ring is clean. Ensure o-ring is properly seated in the cover o-ring groove. Ensure o-ring sealing surface is lubricated with “Jack’s 327” and that strainer cover is locked firmly in position. Lubricant will help to create a tighter seal. 2. Loose connections on suction side. Solution: Tighten pipe/union connections. NOTE -Any self-priming pump will not prime if there are suction air leaks. Leaks will result in bubbles emanating from return fittings on pool wall. 3. Leaking O-ring or packing glands on valves. Solution: Tighten, repair, or replace valves. 4. Strainer basket or skimmer basket loaded with debris. Solution: Remove strainer housing cover or skimmer cover, clean basket, and refill strainer housing with water. Tighten cover. 5. Suction side clogged. Solution: Contact a qualified repair professional. Block off to determine if pump will develop a vacuum. You should have 5” - 6” of vacuum at the strainer cover (Only your pool dealer can confirm this with a vacuum gauge). You may be able to check by removing the skimmer basket and holding your hand over the bottom port with skimmer full and pump running. If no suction is felt, check for line blockage. a. If pump develops a vacuum, check for blocked suction line or dirty strainer basket. An air leak in the suction piping may be the cause. b. If pump does not develop a vacuum and pump has sufficient “priming water”: i. Re-check strainer housing cover and all threaded connections for suction leaks. Check if all system hose clamps are tight. ii. Check voltage to ensure that the motor is rotating at full RPM’s. iii. Open housing cover and check for clogging or obstruction in suction. Check impeller for debris. iv. Remove and replace shaft seal only if it is leaking. Low Flow – Generally, Check For: 1. Clogged or restricted strainer or suction line. Solution: Contact a qualified repair professional.

Undersized pool piping. Solution: Correct piping size. 3. Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). Solution: Sand filters – backwash as per manufacturer’s instructions; D.E. filters – backwash as per manufacturer’s instructions; Cartridge filters – clean or replace cartridge. 4. Air leak in suction (bubbles issuing from return fittings). Solution: Re-tighten suction and discharge connections using Teflon tape. Inspect other plumbing connections and tighten as required. 5. Plugged, restricted, or damaged impeller. Solution: Replace including new seal assembly. Noisy Pump – Check For: 1. Air leak in suction piping, cavitations caused by restricted or undersized suction line or leak at any joint, low water level in pool, and unrestricted discharge return lines. Solution: Correct suction condition or throttle return lines, if practical. Holding hand over return fitting will sometimes prove this point or putting in a smaller eyeball fitting. 2. Vibration due to improper mounting, etc. Solution: Mount the pump on a level surface and secure the pump to the equipment pad. 3. Foreign matter in pump housing. Loose stones/debris hitting impeller could be cause. Solution: Clean the pump housing. 4. Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage which will allow chlorinated water to seep into bearings wiping out the grease causing bearing to whine.
