Some Common Pool Heater Problems

Troubleshooting and installing a heater that is under warranty without proper licence can forfeit the warranty under manufacturer’s terms and conditions. If the heater is out of warranty, it’s cheaper to do it yourself. In this article we will cover some common swimming pool heater problems.

Heater Won't Ignite

The failure of the heater to Ignite is the most common problem with pool heaters.

  • Make sure that the thermostat is set to a higher temperature than the existing water temperature.

  • Check the pump and filter and clean them if necessary.

  • If your pilot is not lit, check the air supply, gas pressure and proper venting. Make sure that the pilot tube is not clogged and is intact . For MV heaters, if the pilot doesn’t stay lit, check output on the Thermocouple.

  • If the gas supply valve is off, then turn it on because without gas, the heater will not operate.

  • Make sure that your valves are open, to not prevent the water flow.

Low Water Flow

For the Heater to operate smoothly and efficiently, it’s important that the pools system maintains a consistent water flow. Manufacturers provide pressure sensors in the swimming pool heaters. These sensors monitor and detect changes in the flow of water.

In some cases you may see a” low water flow “warning pop up on your LCD screen of the heater. You may notice your heater is not pushing out as much water as it should.

This is a very common problem. If there is no water flow, your heater will not start so you have to ask yourself some questions which are given below –

Have you cleaned your filter lately?

  • On your filter’s pressure gauge, monitor your PSI reading. If it is too high, clean your filter.

  • Increasing pressure goes along with the decrease of water flow.

Is Your Pump Basket Dirty?

  • Check your pump’s strainer basket. Remove the basket and clean the debris with a hose.

  • See that the pump basket and lid are in good condition and have no cracks.

Do You have Many Water Features Operating Together?

  • The pool pump can move a certain number of GPMs, so too many water features will dramatically decrease your water flow.

  • If possible, you can replace the motor with a larger one.

  • Close the water features, alternate them till the pool heats to the desired temperature.

Defective Pressure Sensor /Switch

  • The main purpose of the pressure switch is to ensure that the water is flowing through the unit before it allows the heater to turn on.

  • The main purpose of the pressure switch is to ensure that the water is flowing through the unit before it allows the heater to turn on.

  • Test the voltage reading with a multimeter, on the pressure switch.

  • If necessary replace the pressure switch.

Using Low Settings On Your Variable Speed Pump?

  • The heaters require a minimum GPM flow for operation. If you are running a variable speed pump on low setting, you should meet the minimum GPMs for your heater.

Pool Heater Turns ON And OFF

  • If the swimming pool heater is cycling on and off, it is an indication that the power supply has some issues. It isn’t always the case, however there are other factors that can contribute to your heaters on and off cycles.

The Pool Water Chemistry Accurately Balanced?

  • The pool water chemistry is the leading cause of equipment failure, mainly pool heaters.

  • Before adjusting your chemical levels, test your water. If you are unsure, refer to the heaters manual for the recommended chemical levels.

Have You Checked The Pressure Sensor, Thermal Regulator And The High Limit Switch?

  • Check these parts for scaling, corrosion and any electrolysis issues.

  • If the thermal regulator, pressure sensor or high limit switch is faulty or defective then better replace it.

Have You Cleaned Your Filter?

  • Dirty filter causes low pressure and results in the heater’s pressure switch to turn off. Filter prevents the heater from firing and causes your heater to shut off before warming the water to the required temperature.

When The Last Time You Checked And Cleaned The Heat Exchange?

  • Deterioration of the heat exchanger impacts your heater’s operation.Check your heat exchanger for chemical or sanitizer damage.

Pool Heater Is Not Heating

  • Sometimes the pool heater ignites but does not reach the required temperature or it does not generate heat at all.

Check Your Temperature Sensor

  • Make sure that the temperature sensor has been installed correctly and is in good condition.

Double Check The Thermostat Setting

  • Set the thermostat to a high temperature

Was The Pool Heater Sized Properly?

  • If the heater is undersized, it will face problems heating the pool up. It is always recommended to oversize your pool heater to minimise the time to heat the pool.

Pool Maintenance Tips Every Owner Should Know

Check The Quality Of Water:

The first thing you need to know when you maintain a pool, is to test the water quality often and add the right chemicals to the water. You must keep the chlorine levels consistent all the time. Adding Chemicals to the swimming pool is the most important thing to maintain it.

A pool without the right chemical balance can have bacteria, look murky and can be dangerous to swim in. At least once a week the water quality should be checked during the summer months. The pool should also be checked during winters but it can be less often.

The pH should always be between 7.4 and 7.6. If there is an off balance pH it may cause calcium build up around the sides of the pool and other problems, so it is important that you maintain it well

Clean The Filter:

when maintaining your pool, the next thing you should take care of is to clean the filter regularly. You need not clean the filter as often as you check the Chemicals, but still it’s important to do, to make sure that your pool looks good and works properly.

Depending on the pool conditions and the weather you may clean the filter every three to six months. After a heavy storm, it is better to check the filter. Heavy rain and bad weather can lead to filters needing to be cleaned sooner.

Clean Various Baskets And Collection Pots Third Point:

Along with the pool filter, you have to check the other baskets and collection pots that your pool has. First of all clean the hair and lint pot on your pool pump. To do this you have to turn off the pump and then release the system pressure.

Check The Level Of Water:

Next thing to do regularly, to keep your pool in great shape is to check the level of water. Very low water levels can create problems in the pump and cause it to run dry or burn up. Too high water level can also be a problem as it can cause the skimmer door to not work as it should.
