Product Information

Fault code F.00 indicates an interruption in the flow sensor. This could be due to the NTC plug not being plugged in or coming loose, incorrect connection of multiple plugs on the PCB, interruption in the cable harness, or a defective NTC sensor. How to fix Vaillant Boiler fault code F.00 Low water pressure will affect all boilers at some point in their working life, and your Vaillant boiler should be monitoring the water pressure in case it drops below the normal level, which is typically 1 – 1.5 bar.

To resolve this issue, inspect and clean the ignition electrode. If the corrosion is severe or cleaning doesn't fix the problem, it may be necessary to replace the ignition electrode. Vaillant Boiler Fault Code F.61 - Fuel valve actuation What does Vaillant Boiler fault code F.61 mean? If the boiler doesn’t reset, don’t keep pressing the reset button as this can cause further damage, but call out a Gas Safe registered engineer. So alternatively, using a Vaillant specialist, providing a sensibly-priced one-off labour charge to replace the Water Pressure Sensor, thus resolving the F.75 problem, would seem a better proposition.Your system’s flow rate is simply the rate at which water comes out of your taps or the showerhead. If this rate is slow, then it is considered a poor flow rate and will be seen when you first turn the taps or shower on – the water will take time to come out and will then not increase in flow or pressure. This vital component pushes hot water around your central heating system and therefore if it does develop a problem, it is likely that your heating will stop working.

Surprisingly, some of these boilers manage to limp on for a while, intermittently cutting out but not failing completely. Replacing a pressure sensor on a Vaillant combi boiler is easy for anyone who has done any kind of boiler repairs before. After the F.75 code disappears from the display and four short separated buzzing noises are heard as the boiler is going through the pre-firing up procedure, there may be an opportunity to glean whether it is the boiler’s Water Pressure Sensor, or the Pump, that is the responsible part for the F.75 fault. The next most common Valliant boiler issue we come across relates to issues with the gas supply. This will usually result in either an F22 or F27 code showing up on your display panel.

Vaillant boilers come with between 2-5 years of parts and labour warranty as standard but many models can go beyond this when installed by a Vaillant advance installer. To help you find out even more, we've put together a complete guide to Vaillant warranties.

Flow rate describes the rate at which water comes out of taps or shower heads, and a poor flow rate means that the flow of water is slow. How to increase flow rate The gas valve is an essential component in your heating system as it controls the heating of water for your radiators or hot water taps. When your boiler switches on and needs a flame to heat up the water, the gas valve opens up to let enough gas through for the ignition. However, a faulty gas valve is a serious malfunction as it can allow gas through even when it is not needed so never ignore the F62 error code on your boiler’s display. To help keep your Vaillant boiler happily running, we take a look at common Vaillant boiler problems, what those fault codes mean and how to fix them. It is possible that customers may be able to get a useful heads up via the use of the ecoTEC’s user controls, as to whether it is more likely to be the Water Pressure Sensor or the Pump, that is the cause of the F.75 fault. In many cases a Vaillant boiler with water pressure problems is a common reason for a breakdown, faulty pumps and gas valves or frozen condensate pipes. Even in situations where an error code is displayed that is not so common we understand how to apply a suitable fix.

How To Detect F75 Pressure Sensor Faults

If you find your Vaillant boiler is firing up unexpectedly throughout the day, then you have an overactive boiler. This is one of the common Vaillant boiler problems, particularly with the Vaillant Ecotec Plus. We mentioned frozen condensate pipe earlier in the list of Vaillant boiler problems – during the winter it can be a real problem, especially if the pipe isn’t well insulated. How to defrost a frozen condensate pipe When it comes to heating systems, Vaillant boilers have established themselves as one of the most reliable and efficient systems around. However, like any complex machinery, these boilers occasionally encounter technical hiccups that can disrupt their smooth operation. Fortunately, Vaillant has a sophisticated error code system, designed to help homeowners diagnose and troubleshoot common issues. Many of our customers have experienced their Vaillant ecoTEC boilers playing up with intermittent F.75 issues, due to Water Pressure Sensor failures over the years.
