Question about Flow Pool & Spa

1 Answer

Hi, I have an LA Spa with Gecko MSPA-MP with Laing circ pump and heater, the spa will not heat as the circ will not run, tries to prime thens shuts off and does this continually until it finally shuts down. There is flow when it runs and no air locks, will run for 10 mins if flow switch is unplugged and then shuts down. Have replaced temp regulator and hi limit sensor, the only thing I can think of is faulty Harwil flow switch, is this likely and can you test it?

SOURCE: No Heat from Spa

Tcarrigan,

Heater contactors "buzzing": Do you mean normal buzzing or extra loud buzzing? Loud buzzing or chattering can be caused by low voltage to a contactor. If normal sounds, then probably the relays on the contactors is working, but the contacts may be stuck, or burned enough so as not to make contact. First, get a voltmeter and check for 240 volts AC at the heater contactor terminals. If the voltage is low, most likely you need to check the contactors further. Check for dirty contacts, clean if needed. If the contacts are not moving when energized, then you will probably need to replace one or both of the contactors.

I had a similar problem and it turned out to be the solder connections on the control module. The connector that is soldered to this board (comes from the gas valve) needed to be re-soldered.

SOURCE: E04 message on MiniMax NT 400 DV..Help!!

Your EO4 message tells you you have a fan problem. So ether your fan is diying wich you would hear or you have a bad presure sensor in your exaust. A new fan is a little pricey but the sensor is reasonable for heater parts. I can't be sure but I believe it ether screws onto or into your exaust and it just plugs on to your control board. If your sensor is going bad their is a reason and this should be addressed. It should be in your by-pass or your gas pressure. But as far as a new heater, not untill you have water coming from the cabnit. It is sometimes easer to sell new than keep up with new, Good luck let me know how you do.

SOURCE: my hayward heater gives a LO error when trying to

One of your limits is not working or not wired up. An easy way to check the limits - Water pressure switch, Hi limits, air pressure switch all of which have 2 wires going to them. Unplug one item and connect the 2 wires together ( paper clip works fine ) Then retest, if problem does not go away remove paper clip and reconnect wires and move to the next limit. The limits are located in the black plastic header. Always make sure water is flowing through the heater at all times while checking the limits.

Pump does not shut off and timer does not stop after the 20 minutes.


What is on?
If equipped with a Small (Laing or Grundfos branded) circulation pump, these are normally Constant Duty pumps running 24-7
If not and it is your Low Speed running, then your switching mechanism has failed. This is normally the symptom of a spa that has a Mechanical Timer. Does your spa have one? If so, it may have failed, replacement should take care of it.
If electronic, then a relay has fused together on the PCB, and the only proper repair is replacement of that Board.
Now... If you are referring to HIGH Speed (you were not very specific) then this is a problem! A serious problem that needs correction ASAP!
Why?
Because a pump that runs constantly on high speed will STILL HEAT the water long after the heater turned off! Until it boils!
That is if the high limits have failed as well, don't think it doesn't happen, it does!
A very potentially Dangerous situation.
Kinetic energy or friction of water moving through the plumbing occurs! There is a restriction of the path/flow of water through the spas complete plumbing system, but the pump pushes it still no matter what, over and over. This is energy transferred to the water.
Good Luck.

How do I prime the pump


this code generally indicates that there insufficient water to heater. either there is an air lock somewhere in heating circuit (try loosing union a bit to bleed any air out) or the circ pump is inoperative. Check to see if operating. If water not flowing through then try to force garden hose stream from outlet in spa towards circ. pump.

A heavy water leak as soon as we turn on the jets. Is it one of the jets leaking or something else?


circ pump and booster pumps are different. circ pump is on during filtration cycles aswell as the heating element. booster pumps run the remaining jets. if you are only losing water when the jets are turned on, then start looking under the tub skirt for leaks within the jets and the plumbing

How to fix balboa EL2001 spa


Hi,

OHH would be the Hi Limit sensor. OHH is an overheat event...
Check the followng:
1. Low GPM.
2. Low Water Level.
3. Blocked Suction Fitting.
4. Blocked Skimmer.
5. Dirty Filter.
6. Too Many Closed Jets.
7. Closed Slice Valve.
8. Heat Related Pump Not Running.
9. Heat Related Pump Not Primed.
10. Malfunctioning Impeller.
11. Incorrect Heat Related Pump.
12. Circ System Misconfigured.
13. Sensor Malfunction.

As you have already changed the sensor it is likely to be one of the others points. Hope that helps.

What causes these pumps to stop working? there is power to it, this is not the first one that needs to get repalced


Hi, these pumps work hard 24/7 and unless they have good ventilation they can overheat. They can also overheat if the prime for the intake is gone and and the pump is allowed to continue running dry. The bottom line is that these pumps get hot and electronics under the stress of high temperatures is never a good mix. One other consideration is the wiring that supplies the pump with current. Make sure that the cable is the appropriate gauge and for the size of the pump as well as the distance from the main power source. These things, if not considered properly will also lead to overheating. Hope this helps.

Refilled my hottub and now there is a ''FLO'' signal and the heater will not come on. Pumps and jets work fine.


simple fix its one of two things you did not prime the spa when filling it meaning that u just did not lay a hose in the spa then fill it you always need to prime the heater first along with the circ pump if you do not you will get a thing call airlock which is what it sounds like air in the main circulation pump for the heater.Also could be that u removed the filter while you still had the spa running an clogged the circ pump or it could be the flowswitch. Sounds like u might have a sundance spa an if the flo is flashing its either the air lock or your pump went or its clogged if the flo sign is not flashing then its the flowswitch but in that case w/a solid flo nothing would b working. To fix the airlock just shut the power down an take your hose an force water into the intake side of the filter area this is what u should always do 1st when you fill it that how you prime yuor pump an when fillin it all the way it best to fill it through the other end of the filter just put the hose into the filter tube w/the screw on it.IF THATS NOT IT THEN FEEL YOUR CIRC PUMP IT WILL BE THE SMALLEST PUMP IN THE SPA IF U CAN NOT TOUCH IT FOR MORE THEN A FEW SECS. THEN IT WENT ON U OR IT CLOGGED
