Hi,

The pressure sensor on this model is AFTER the integrated dryer.

If there is a blockage in the dryer, the compressor pressure will rise until the safety valve blows.

The most common problem here is that the dryer temperature is below 0 and if freezes shut.

Please check the dryer temperature first, what is it?

Best,

Cas
