It works
I got the F75 error code and researched solutions and causes. The answer seemed to be either the pressure sensor or the pump. The cost of a pump is about 200-250 so I took a chance that it was the cheaper option. I ordered the sensor and it was here the next day. Fitted it a day or so later and the problem is solved. Some tips when messing with the boiler…. Turn it off and drain it. This muppet forgot to drain it🤦♂️ so ended up with a lot of water in my face. Also damaged the PCB so had to replace that too. Managed to get a PCB for a good price too. All in all, replacing the sensor and PCB myself cost less than a heating engineer call out fee so I’m a happy chappy. Also learned how to drain the boiler for any future events.

No more F75 error code
Product arrived swiftly, and was fitted to my boiler by myself the next day. Quite an easy job and 1st time doing it on my 4 year old boiler. Been told this is a common fault so expecting to do it again in a few more years?? For a long while we was waking up to the boiler flashing a F75 code, so each morning I would reset the boiler, strange it only happened over night and never during the day?? Now the pressure gauge on the cold water intake and the boiler read the same, before there was a 1 bar difference hence the pressure sensor being faulty. So far so good, only grumble is the part looks like a copy and even the bag had nothing regarding the boiler make etc on it? But if it works and lasts years I am happy! Would recommend part to others

Does the job.
This review is not only about the part but also about the seller. Item arrived and the clip and ring was missing from the package. I contacted the seller to let them know and they responded very fast and sent the bits I needed straight away. So 5* to the seller! The part itself fixed the problem perfectly. Boiler was showing F75 fault. Pump was fine so knew it was this that was needed. Genuine part. Overall very happy not only with the item purchased but with seller communication and reaction. Definitely recommend! Thank you.

Works a treat
I bought this for a Vaillant Eco Tec plus 624 as I kept getting a fault code 75 (low water pressure) & my heating wouldn’t start, even though the digital screen showed 1.6 bar pressure. I YouTubed how to change & voila! Works a treat. Now my heating comes on when showing 1.4 bar.

Worked Perfectly
Diagnosed the fault from the boiler error code, drained down the system and replacing the connector was simple. Saved a good bit of money on a call out.

Just the job
Boiler was giving F75 error. Checked the pump, that was fine so other option was pressure sensor. Found this one, genuine part, great price and fast delivery. Easy to fit and did the job perfectly. Great seller, great service!!
