Pentair MasterTemp 400 Common Problems
Ignition Problem
So many customers have mentioned that they have a problem with the ignition of the heater. Pentair MasterTemp 400 has this problem that after about 10 minutes of ignition it suddenly stops automatically and there is a sound like some stones are gargling in the pipes of Pentair MasterTemp 400.
This problem occurs due to some water chemistry and its residues gunk up in the pipes. Basically, this problem occurs when there is no proper water flow, then Pentair MasterTemp 400 gets too hot from inside that it shuts itself off.
Troubleshooting
First, make sure that your heater is turned on properly. Secondly, check if the temperature is set correctly. If these are not the problem, make sure that the pilot is turned on properly, if not, then check the gas supply is proper.
Do check that the pilot pipe is not clogged. This problem can be eliminated if you clean the water. Make sure that the heater is consuming soft water. If your heater uses hard water then residues can block up the pipe, and the heater will turn itself off.
Positioning the Heater
Some of the customers face problems with the positioning of the headers through which water flows in and out of the heater, and the question in their mind comes what if we have to take out everything from the heater and fix it again according to the pool positioning? But the good news is this can be fixed according to the area where your pool is located. It is just simple and easy.
Troubleshooting
If the headers of the heater are on the right, but you need them to be on the left side according to the position of your pool then what you have to do is “Rotate.” Just Rotate the heater to the left side, and the headers will move to the left.
Now rotate the top board where the button panel is so that Pentair MasterTemp 400 works properly again. You don’t have to physically take out everything inside and then put it back.
Not Heating Properly
What’s the point of having a heater when it’s not heating? Many customers complained that our pool/spa heater is not working properly. This is a common problem seen in Pentair MasterTemp 400, but this can be surely corrected.
Troubleshooting
The troubleshooting is easy, you have to make sure the state you live in isn’t too cold because Pentair Mastertemp 400 works with heat pumps which means that it doesn’t use propane gas but consumes heat from the atmosphere. If the atmosphere is cold enough, then it would be difficult for Pentair MaterTemp 400 to create heat.
If this is not the reason then check the pool heater size; it should be according to the size of your pool need. If it is undersized, there will be a problem with heating. You should also inspect your Thermostat settings and set them to a higher temperature. In some cases, the thermal regulator needs to be changed.
Temperature Display
In some cases, a heater fails to display the correct temperature. This is also a common problem that is seen in Pentair MasterTemp 400. This can be sorted out easily.
Troubleshooting
You will need to change the thermostat if you see any fluctuations in a temperature display. Remove the panel behind the headers. If you observe keenly, you will see a thermostat just above the high limit switch. Take it out by pulling it with the pressure required with the spring attached to the thermistor. Now place a new thermostat carefully and place the spring back in the right position.
Low Water Flow
For heaters to operate efficiently it is necessary that the pool system maintain the flow of water. If the water level is low then it would be difficult for the heater to work properly. Check to maintain water levels by keeping some points in mind.
Troubleshooting
Check if the filter is cleaned or not. If the filter is cleaned and does not show PSI at a high level, then check the pump’s strainer basket. If it is dirty, then clean it with a hose and make sure that there are no cracks at the lid of a basket.
The most important point to keep in mind is that the sensor is not defective. Test the voltage reading on the pressure switch with help of a multimeter.
