Chefman RJ11-17-GP Precision Kettle not getting hot. When turned on and temp set it just shows the current water temp and doesn't even try to heat the water.

switch or power failure need to test

Check your filter cycles and switch spa into Standard Mode as you have it in Economy. (In Economy mode it will only heat during the filter cycles).
If the Ecn or Ec Message is Alternating with the Water Temperature on the Display, the Spa is Operating in the Economy Heating Mode.

If the Ecn or Ec Message is ON Solid (Not Flashing) on the Display, the Spa is Operating in the Economy Heating Mode, but there is No current water temperature because the Spa is between Filter Cycles.

Ecn or Ec is Alternating with Temp:
The Spa is Operating in the "Economy" (Ecn or Ec) Heating Mode.

The Water Temperature is Sampled Only during Programmed Filter Cycles. The Heater will Only operate and Heat up to Set Temperature during the Filter Cycles. The Water Temperature will probably drop Below Set Temperature between Filter Cycles. Other Heating Modes are Standard, Standard in Economy, and Sleep Modes.

Ecn or Ec is ON Solid (Not Flashing):
The Current Water Temperature is "Unknown" (- - - or - -) while in Economy or Sleep Mode.

Between Filter Cycles, while in the Economy or Sleep Heating Modes, the Pump has not turned ON and the Last Water Temperature is not Current. To read the Current Water Temperature, either Change to Standard Heating Mode or turn On the Heating Related Pump, and wait at least 2 Minutes.

How big a pool? You normally will not notice a temperature rise immediately. On average, swimming pools will see a one degree rise in temperature every 45 - 90 minutes.

It sound like the temperature sensor that switches the kettle off when it has reached the correct temperature is faulty. It would probably be cheeper to replace than repair

This is because there is a current leakage between the live and earth terminals of the kettle.
You see, if current leaks from live path to earth, you will get an electric shock when you touch the outer metal surface (because the metal part is earthed). To protect you, the trip switch will cut off the electricity supply.
You can try drying the kettle in hot sun. This is because the current leakage is most probably due to water leaking in to the circuitry.
You can try replacing the heating element, if it is available in the store. Otherwise do not use it. That's better for your safety.

there should be a dial of some kind on the front of the water heater that controls the water temperature turning it up a notch or two beyond its current setting should make the water temp hotter

your condensation pipe may be frozen get a hairdryer on it or a hot kettle that should sort it thats the whit pipe on the left usualy plastic

Make sure the hoses are connected correctly to the water valve on the machine. The connections will be marked with an "H" and a "C".

Given they are correct, most current washing machines have and auto temp feature on the water fill. It allows even cold water settings to bring in some hot water to make sure the water temp is hot enough to efficiently disolve your laundry detergant. The preset temps are usually around 75* for cold, and 105* for warm. Hot water comes in at whatever temp your household water temp is.

I use a solution of vinegar and water (1:1) and boil it in the kettle, to remove mineral deposits from the metal heating surface (We do the same with the percolating coffee maker and run it through several times)... It seems to take any residual tastes out of the unit and possibly also cleans the plastic parts that it touches (I believe it does).
By the way... WHO thought it was a good idea to heat apple cider in an electric kettle. Sorry but WOW
