A call out fee and labour cost may apply to field services.PROBLEMS & POSSIBLE CAUSES;20. Light Flashes “No Water” or “Failure”1. This normally indicates that the pump has no water, either because the tank is empty or the pump has “lost prime” it has run dry.2. The pump is fitted with an AUTOMATIC RESTART controller so it will attempt to re-start itself several times. This is normal, it doesnot mean the pump is faulty. Refer to point 19 a) to k) of the instructions.NOTICE: tank level indicators are not always accurate!! Check inside the tank to be sure of the water level.21. Pump does not run or motor runs for a short time, then stops1. Circuit breaker or Safety Switch is off or fuse has blown > in a SAFE manner investigate why this has occurred, by process ofelimination > do not assume it is the pump > if you cannot do this safely, have a licenced Electrician check and rectify it.2. Water level in the tank is too low > Top up or use alternative supply > turn pump off until the tank fills3. Electrical components have been flooded > It is likely that the pump will need to be replaced > in a SAFE manner investigate whythis has occurred, by process of elimination > do not assume it is the pump > if you cannot do this safely, have a licenced Electriciancheck and rectify it.4. Pump plug is not connected properly, or has been flooded or wet > Isolate power at main switch, remove plug & allow to dry. If theproblem continues, contact a licenced electrician to check the cause.5. If all of the above are OK, the pump might have overheated and triggered the thermal overload switch > Turn it off and wait 30minutes for it to cool down and turn it on again > If the pump does not operate normally, investigate why, it might be blocked withdebris, or the Y-Strainer/Prefilter might be blocked > flush clean and re-assemble.22. Pump runs but does not deliver water or only a small amount of water1. Check valve is installed backwards, arrow on valve should point in direction of flow > have the installer fix this.2. Discharge shut-off valve/ball-valve / gate-valve may be closed > open the valve.3. Impeller or volute openings are fully or partially clogged or it might be blocked with debris, or the Y-Strainer/Prefilter might beblocked > flush clean and re-assemble > if it is the pump, disconnect from the power supply, and if you are competent to do so,disassemble the pump and clean. If not, have a pump technician do it for you.4. Pump is air-locked > Start and stop several times by turning it on and off with 20 seconds between. If this does not work, see belowregarding re-priming the pump5. Vertical pumping distance is too high - Reduce distance or upgrade to a larger pump.6. Foot valve blocked > Clean or replace the FOOT valve7. Tank too low water level > Check the suction and water levels23. Pump runs and does not stop or runs when no taps are in use1. In most cases this situation it is due to a leak in pipework or leaking toilet cisterns or underground pipe leak (wet soil, muddy, grassgrowing well!) > it is not a pump fault > ascertain by process of elimination what is leaking > the only sure way to check toilet cisterns isto turn them off at the stopcock which is usually under the cistern as most of them will not run into the pan > close the ballvalve / gate-valve on the discharge side of the pump, does the pump now stop > something is leaking it is not a pump fault.2. There could be debris inside the Pump Controller > open all taps fully to try and flush it out > if this does not work disconnect fromthe power supply and [a] remove the pipework off the top of the controller there is probably some debris in the brass “popit valve”that is in the top of the controller, carefully remove the debris > if it is not that disassemble the pump controller and clean, or have apump technician do it for you.24. Pump not pumping properly1. Too high head or pump under specified > Check specifications.2. Too low water level > Check the water level in the tank, tank level indicators are not always accurate3. Loss of prime > Check foot valve (if fitted), re-prime the pump.4. Leakage of inlet pipe > Check the inlet pipe is not taking in air, check all joints.5. Inlet Pipe has rise and fall (Dips) or has too many elbows or is blocked > Fix suction pipe so it is both perfectly straight and level,OR rises all the way to the pump, or turn the pump off and wait for the tank to fill more > NOTE: if the inlet pipe is not straight to thepump it is most likely that you WILL get airlocks in the pipework especially when the tank has low water, this is NOT a pump fault >turn the pump off until the tank fills to have 500mm depth or more.6. If a check valve has been installed directly on the discharge of the pump controller, this may cause the pump controller tomalfunction > Move the check valve to a different position.
