vaillant water pressure sensor replacement f73 f75 error eco-tec pro

this is NOT the only cause of this fault code... just a common one. others include pump, low pressure, blockages, filter issues, potentially expansion vessel problems.... (non exhaustive...) The point of the video is to show how to replace a water pressure sensor - which is a fairly common fault. it should be done by a gas safe reg'd person.

Just found your channel after working on Ideal logic looking up service mode.
