The pressure switch has to be checked.Either the switch is got loose or its worn out and the switch needs replacement.
If the switch is checked out OK then check the valve which gets command from the switch to open and close.If the valve is cracked or blocked it needs to be checked and replaced.
And for temp problem the heater connections needs to be checked.Also the heating coils and element needs to be cleaned and checked.
Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

Siemens dishwasher isn't washing dishes clean and leaves some detergent in the door


Hello. From what you're describing, you might have low spray pressure(due to a clogged filter on the main pump, if your model has a filter). I really need the model number to help you accurately. Also, the water temperature may be too low to dissolve the detergent-- DISHWASHERS LIKE HOT WATER! The minimum temp for all the detergents is 120 degrees or hotter! I tell all my customers to turn on the hi-temp wash, or temp boost, or whatever the manufacturer calls it on every wash cycle! Otherwise, you're at the mercy of whatever temperature water got put in the tub. ALWAYS RUN THE HOT WATER IN THE SINK BEFORE TURNING ON THE WASHER. Modern units take very little water to fill. By the time the hot water makes it to the washer in most cases, it's already running on tepid or cold water--especially in the winter. I hope I helped you!

2000 Gallant. Installed new radiator, thermostat, and water pump. Why does temp gauge read hot when it's not?


Disconnect the temperature sending unit wire connector for the gague ( not the one for the computer ) with the key on. The temp hand should stay on cold mark. Next, ground the wire and the temp hand should go to full hot indicating the gague and wiring to it are ok. If ok suspect a faulty temp sending sensor if the cooling system is full and properly bled

Why wont hot tub heat with jets on losing temperature on 110 volt


My first question would be about the outside temperature. What is the outside temperature?
Hot tubs that are designed to operate on 115v only have 1.5kw heaters and if the outside temperature is below 50 deg F they tend to not keep up to 103 deg water while being used. They are also designed to not heat while the high speed pump is operating.
Does it stay up to temperature on a normal basis?

My Oaisis II hot tub stays at 103 and now it's dropped down to 68 degrees for the past 3 days? Could there be a problem with my heater element? Or is there a sequence of resetting the temp buttons on top...


Information on the care of your product and troubleshooting is available here:

http://www.oasisleisure.ca/customer_care/SpaCare.html

Did you have a recent power outage? It is necessary to reset the temperature after a power outage.

Check the temperature setting on your hot tub; if it has defaulted do to a power outage reset to the desired temperature. If it is still set at your desired setting and is operating at 68 degrees then there is a problem that is preventing the tub from reaching the set temperature.

Some possible causes and actions are:

Pull filter (see if light comes on) / Replace filter
Knife valves not fully open / Open knife valves

Pressure switch cut of calibration / Adjust pressure switch
Faulty Pressure Switch / Replace pressure switch

Air leak, check pump suction line / Tighten pump union
Heating element corroded / Replace element

Faulty control panel / Replace panel

Qca Spa pumps and blower will not come on, water down to 35º f


Ken,

You need to contact a hot tub technician/engineer as you clearly have issues.

'ICE' means that the water temperature is too low and therefore the pumps will be turned on to prevent freezing within the plumbing. Depending upon the spec and settings, the heater maybe disabled during 'ICE' condition.

'ECON' is Economy Mode. If you have a mode button, keep pressing it until you see 'Stan' on the display. This will put the system back into the standard mode.

'FLO' means that there's insufficient flow of water through the heater, or non at all. 1) Check the water level - top up if low. 2) Ensure that all jets are open and flow water - if they don't you may have a pump issue. 3) Remove the filter(s) and see whether or not this clears the fault, if so clean or replace the filters.

'COOL' is displaying because the set temperature is much higher than the current water temperature.


As I mentioned at the start, you really should get someone to take a look at your hot tub. You may have a few issues that need resolving.

Regards,
Ian.

Jet pump will not shutt off after I replaced heater relay. Tub is a hot springs landmark with an IQ2000 panel the year is also a 2000


it sounds like the pump relay may be stuck closed. Also check the temp readout, if it thinks the water is too hot it will try to cool the water by running the jets and sometimes the blower as well.

you need to replace the heater core and pressure text the radiator cap, replace if it leaks down go to a parts store to do this also you need to replace freeze plugs if you don't they will blow and ruin the engine,a slo check that the water pump is not bad, loosen the pump belt and see if you can wiggle the water pump with fan connected, if you have any play replace the water pump. and add new anti freeze.

Pump is running ever 5 minutes. The heat in the


Sounds as if the 'mode' for the tub is set to sense the temperature of the water. see if there is a setting on the control box to a 'timed' setting for filtering and heating instead of controlled by the temperature setting. the problem is the the control box is away from the water and when it calls for heat it is because the water is cooler there than in the hot tub. so when it calls for heat and the water starts to circulate it gets the hot water from the body of the hot tub and then shut down because it senses the 'hot water'. make sense?

Hot tub will not stay warm


You must keep your circulator pump running if you want the water to stay hot. The water is being heated inside the pipes but it isn't getting circulated until you turn on the jets pump.
