Have you primed the pump by bringing water down to the pump? It will not work if the supply line is not filled with water from the pool.

SOURCE: no water flow in pump

The impeller in the pump unit could be broken. If there is water flow into the pump, but no flow back to the pool, the impeller is most likely broken.
Make sure the hoses are not hooked up backwards.

SOURCE: pool pump intex 51 pumps water but return flow is low

if you cartridge is completly clean then start by disconecting the out tube that goes to the pump housing
sometimes debris gets caught there entering your pump.
a little hair causes other things to back up

once you are satisfird that those 2 things are ready then close it all up and open the bleeder cap on top of the cartridge holder

Now let water in from the suction side
when water starts coming out of the bleeder cap then open the return side
Now turn on the puimp
let it run for 20 seconds and then close your bleeder

Should be working fine after that.

dont forget to leave the bleeder cap alone on the bottom of the canister unless you are draining the water from the canister to clean it. As soon as you are done close it back up

SOURCE: no water flow though pool pump

Check and see if all valves are turned in the appropriate positions. Sometimes homeowners forget to switch the valves from spa mode to pool mode or vice versa and wonder 'why isn't my pump pushing water?'. Another thing to consider is what type of pump you have. If you have an owners manual, check and see if you have a flooded suction pump or if it's self priming. You may need to dump water into the trap before seeing water flow through. You may also have faulty valves or check valves. Check your filter and make sure all positioning of valves are in proper place. If all else fails...call a pool professional. These small self performing tips are just something to consider to save some money in the long run in lieu of calling someone that may poke your eyes out with a service call and something as trivial as turning a valve. Hope this helps!

The heather computer indicates:Flow and does not come on


Without knowing what heater manufacturer or model, or whether this is a burner style furnace or heat pump, I would surmise a guess that you have a flow issue, a restriction in your water flow. Most water flow issues are corrected by cleaning the filter.
many people who are not in the know, or don't understand these type of things, always ask what does the filter have to do with my heater?
heaters need to have the proper amount of the water flow through them for them to fire safely and efficiently. When that water flow is reduced or restricted there is a safety sensor that senses improper water-flow, and will not allow that heater to operate. Remove the restriction, and that specific sensor that senses for proper waterflow, will allow the heater to operate.

Will the water pump work on a mercury outboard motor 7.5 if the lower unit oil is low


First things first, never let your lower unit lube be low. It should be changed every 100 hours of use, or at least checked after big trips with prolonged use. If it is low, but does not look grey, milky or burnt, then just add from bottom plug until it comes out of the top plug. Now, the water pump is completely separate from your oil situation. Whether or not your motor has what is called a "pee stream" does not necessarily mean you have a bad water pump. Often times the water flow indicator, or "pee stream" on your engine will be plugged, which is okay, it\'s just an indicator. However, if you were to test run your engine on a garden hose at home, and there was no flow out of the propeller hub, which is actually where the exhaust flow exits as well as your cooling water, then you\'ll need a new water pump impeller and/or possibly a water pump kit. This should be around 40 to 75 dollars in parts, and about 1.5 hrs in labor if you were to take it to a shop.

Display on hot tub says low flow


Low flow is an indication of not enough water flowing through the system.
Check the flow by removing the filter from the spa and see what that does for you. Many times even brand new filters have enough tiny fibers from the manufacturing process to not let enough water flow through to operate a spa.
If you remove the filter and it still has a flow issue then make sure the gate valves on either side of the pump are completely open and no restrictions.
Also make sure the water is full in the spa.

My system keeps flashing the 90 code indicating low water flow. My pool is full. What's wrong and how do I get the system to run normal? I just set the pool up and it has flash this cood from the...


Most low flow alarms are caused by the pump stopping before the chlorinator cycle ends. You must set the chlorinator hrs between the pump cycle. Start and set your pump cycle, wait at least15 to 30 minutes and then set you chlorinator hrs and make sure to it completes it's cycle at least 15 to 30 minutes before the pump cycle ends, If your pump turns off before the chlorinator cycle ends, you will get a low flow alarm......

I just bought my hot tub, it shows ''FLO'' on the panel when i turn it on. I did every thing they say on the panflet but it still doesn`t work. Anything else i should do??


The problem is that the flow switch for your water heater is indicating no flow. Therefore your water heater will not operate. Without proper water flow your heater will burn up. Check that your valves are open. Check that your pump is running. Check that your filters are properly installed and not restricting flow. Check the wiring to your flow switch and make sure the flow switch operating properly (i.e. put a ohm meter across the contacts and see if you have continuity when the switch closes).

Our system continues to give a 90 code reading even though we have a big enough filter pump to push enough water through the system. Everything is tight and the system is clean. how do we correct this...


Code 90 indicates that the water flow rate is not high enough for the system to operate properly. This is measured by a white plastic piece hinged from the top of the pipe. As water flows by the plastic piece gets pushed back and up against the top of the pipe so that it touches a sensor. A couple of solutions are as follows or a combination of these:
1) make sure that all pipes and filters are clean and clear. Leaves or other stuff will slow the water flow.
2) check that the clorinator is clear of any blockage or dirt.
3) unscrew the flow meter and pull out to check that the hinge is clean and the plastic piece moves freely.
4) when you put the flow meter back in place try turning it ever so slightly which might make a difference. This has worked sometimes for me.
5) make sure that the clorinator is level. I tilted my unit so that the inlet side is slightly higher than the outlet as an experiment and this works as well since I was trying to get the flow valve to travel less distance.(it's a geometry issue)
6) make sure there is no air stuck in the lines. Try lifting the pipes/tubes to move air out and make sure you bleed your pump to ensure that it is full of water and there is no air trapped here that would reduce flow.
7) try taking any nozzle off the hose going into the pool. These may slow the flow coming into the pool and cause back pressure in the pipes.
8) I have a solar panel with a bypass valve. The clorinator only works when I run the water using the bypass valve so that no water runs through the solar panel. Try running all water only through clorinator with no other devices in line to slow the flow or produce any restrictions.
9) Try running the clorinator but take out the pump filter as an experiment. The filter may need replacing. Taking the filter out should tell you if this is the case if the clorinator works without the filter in place.
10) As a last resort check the flow rate requirements for the clorinator and on the pump you have. The pump may be undersized.

Small coffee and coffee buttons flashing, hot water button on solid, water tank and priming butten on solid. I can open steam knob and let cold water run all day, but that's all that happens. What's wrong?


HI
Its your flow meter. If you have a restriction in the intake line the message will not go away. There is a flow meter inside the machine that measures water flow. If the flow meter does not spin when the pump is running, the computer thinks that the pump is not primed. Coffee grounds will get into the intake and restrict the flow meter. If you get a restriction in the water intake (below the water tank, on the machine) the pump may run and water comes out, but the flow meter does not create the jet of water to spin the turbine wheel to send impulses to the computer. You get the ventilate message.
You need to take the flow meter apart and clean it or replace it.
