E05 is antifreeze circuit 1.
It's triggered when the leaving water temperature is lower than the set value in the parameters.
Check the water flow rates or the fridge side for SOG.

Checked pressures 350discharge 110psi suction checked filters and flow valve have to check flow rates

[marc5180]

Do you have a Lennox DS50 service controller to check the parameters

[jonjon]

Marc is on the ball jonjon!
Does your accurate reply indicate you have that manual? (If not I can forward)
Because if so. Marc's diagnostics are correct.
Although i suspect you already know this!

You'd get more information from the service controller Ds50 that plugs directly into the module but by the looks of it, you can also check the parameters from that controller.
