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
