Wiesberg 3-Way Valve Motor RSSE 24 (also RSN, RSNE, RSS 24 and Unical DUA)

If you notice that you have hot water but no heating, or vice versa, a technical diagnosis must confirm if you need the motor of the 3-way valve Wiesberg RSSE 24. This part allows switching the water between the heating circuit and the domestic hot water circuit. If it fails, it can cause both circuits to mix, affecting the performance of your boiler. This motor is compatible with models such as Wiesberg RSN 24, RSNE 24, RSS 24, and others from Unical, including DUA BTFS 24 and DUA BTN 24. A technician must confirm through diagnosis if it is necessary to replace it when these symptoms of malfunction occur.

Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

Find the reference printed on the installed part and check whether it matches the catalogue reference —. If it is not visible, do not identify the part by its shape alone.
Check the full boiler model on its data plate and look for it in the model associations on this page.
Compare the connections and physical body with the original part before installation.
If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Diagnosis and fault codes

Symptoms that require diagnosis in the 3-way valve

The 3-way valve diverts water between heating and domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

01
The boiler provides hot water, but the radiators do not heat up, or they only do so intermittently.
Cause: The valve motor does not stabilize the flow to heating consistently.
Check if the problem persists with the thermostat continuously calling for heat, not just during occasional starts.
02
There is a lack of domestic hot water while the heating is working without any issues.
Cause: The motor does not switch to domestic hot water, often because it does not start or stops before completing the rotation.
Open the hot water tap and listen if the gas valve motor tries to move; if there is no sound, it is not responding.
03
There is a rattling or vibration in the gas valve just when switching from one service to another.
Cause: It is usually due to the motor turning against a worn gear before fitting into its final position.
Check if the noise occurs with every service change or if it has only happened once; if it is systematic, it points to the motor.
04
The motor does not move at any time, neither when requesting heating nor when requesting domestic hot water.
Cause: It is possible that the motor winding is burnt or that it is not receiving power from the PCB.
Before changing the gas valve, measure if the motor receives voltage at its terminals when the boiler requests the change.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
