The best way to find out which solenoid you need is to start by identifying your shower model. Often you can replace the solenoid itself, although on occasion it is sold attached to flow valve/valve housing part. The part may be available in a few configurations depending on the model and manufacturer of your shower. A healthy solenoid coil should have a resistance of over 3.5 Ohms (Ω).Īn example of a Triton solenoid coil with valve assemblyĪ solenoid valve coil is usually fitted on the flow valve, and connected to the inlet within the shower itself.
You would do this by measuring for resistance across the two terminals. It's not always necessary to do this as the symptom explained above is usually pretty indicative of a fault with the solenoid. The health of a solenoid coil can be checked with a multimeter. The coil can break down over time causing these symptoms. When these fail, they usually fail in either an open or closed position, resulting in constant flow when the shower is off, or no flow at all when the shower is on. When the shower is turned off, the removal of current will reduce the the magnetic field and allow valve to close, preventing the flow of water. The magnet moves a plunger, which opens the valve, allowing water to pass through and out of the shower. When you turn the shower on, an electric current is introduced and a small magnetic field forms around the coil in the solenoid. It's important to note that before removing the front cover of a shower, the water should be switched off and the showers electricity isolated (made safe at the fuse box rather than just the isolation pull cord). We recommend to consult a qualified tradesperson before attempting any inspection or work inside the casing of an electric shower. Read on below for more information on how these work. The culprit is usually the solenoid coil. Modified on: Thu, 16 Jun, 2022 at 2:48 PM Does your electric shower continue to flow when switched off? Or, when powered on, there is no flow at all? Perhaps the flow suddenly stops mid shower?
What is the most common type of solenoid Two-way valves Two-way valves This is the. When you run an electric current through it, a magnetic field forms. This way, a relatively small solenoid can be used to switch the valve. Solenoid valves have a coil of wire around a metal core.
The compressed air in this cylinder pushes against the piston and actuates the solenoid to switch the valve. Solution home Technical assistance Fault Troubleshooting How does a shower solenoid coil work? The pilot valve delivers compressed air to a small air cylinder inside the valve.
