    Discoloration of Plaster

    Our plaster is about 4 years old. Recently we noticed that it is discolored in a number of places (only on the bottom, not on the sides or in the spa). The discoloration is dark and a The person that did the replastering claims it is because our CYA levels were too high. Does that make any...

    Pentair 400 Mastertherm heater issue

    Thanks for all of your input. Tested the continuity and it did not change whether the heater button was activated or not. Found a small nick in the wire from the Aqualink and when I cut that out and used wirenuts to reconnect the wire the heater started up when I pushed the heater button...

    Pentair 400 Mastertherm heater issue

    So what you are saying is that I need to test the fireman switch relay. Right now I have the two yellow wires at the bottom of this switch connected with a wire nut and the wires from the Jandy are not connected (which allowed me run the heater from its control). What do I need to do to test...

    Pentair 400 Mastertherm heater issue

    Thanks. Looks like you gave me instructions for the wire replacement. Once I open up the Aqualink is it easy to determine which relay is the heater--follow the wire connected under the heater button to where it is connected to power in the relay section below? If I remember right there is a...

    Pentair 400 Mastertherm heater issue

    I have replaced both of the sensors in the past. The temperatures (both air and pool water) look accurate and were both in the 60s today, well below the temperature set point for heating the pool or hot tub. So I am thinking we are down to the wire and the board. How do I test to determine...

    Pentair 400 Mastertherm heater issue

    I do know how to use a multimeter to check continuity so we have that issue covered :). Also pretty sure I am using the controls correctly, both with the iaqualink and when I put the Aqualink panel at the pool in service mode and hit the heater button. Some questions: Which board am I...

    Pentair 400 Mastertherm heater issue

    Sorry for the delay in responding. Good news is that when I removed the Jandy control wire from the system the heater came on and I was able to heat the pool and the hot tub by using the controls at the heater. When I looked at the diagnostic on the Jandy it said Water Sensor OK, Air Sensor...

    Pentair 400 Mastertherm heater issue

    I am using the wifi IAqualink to control the Jandy. Need to get it reconnected as it got disconnected when I turned the power on and off :(

    Pentair 400 Mastertherm heater issue

    AJW22 not sure how to jump the fireman switch. Here is a picture. Have jumpers. Do I pull the two connections at the bottom (red circles) and jump it there?

    Pentair 400 Mastertherm heater issue

    Thanks for the input. 1poolman1 I did try putting the pool in service mode and turning on the heater. That did not work. The Jandy is showing 67 degrees for the pool, which seems right. Don't know how to run the diagnostic menu in the Jandy--can you point me to a resource to help with that?

    Pentair 400 Mastertherm heater issue

    My heater was installed in May 2020 and it has worked in the past. There are no lights on my heater control panel and it is not working. I check the power and I have 240 coming in. The fireman switch fuse appears to be good and I have power into the board (tested with a voltage tester--three...
