Wilo Pump Motor HB16/6.7-2 - Saunier Duval Themafast F30 - Ref. 0020087276

The pump motor moves a mechanical element in the boiler, typically the 3-way valve, ensuring the circulation of water. This component, manufactured by Wilo and with reference 0020087276, is essential for the operation of the Saunier Duval Themafast F30, among other models in the range. If it fails, you will notice that the heating or domestic hot water does not work properly, and errors such as F.22, F.23, F.24, or F.75 may appear. This motor is installed in boilers like the Themafast Condens F 24 E and the Isofast 21 Condens. A technician must confirm through diagnosis whether it needs to be replaced when symptoms of malfunction or errors related to the pump are present.

Guide

How to check if ref. 0020087276 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 0020087276. If it is not visible, do not identify the part from 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 engine 0020087276

The motor drives the corresponding component of the boiler. These are the typical symptoms and what to do:

Common symptoms and faults

01
There is no water circulating in the heating system or in the domestic hot water.
Cause: The motor drives the pump and the valve, so a fault affects both circuits.
Check that the shaft is not jammed, with the boiler unplugged, before replacing the assembly.
02
A buzzing sound is heard in the pump-valve group but there is no heat.
Cause: The motor tries to turn but does not move the water; it could be air in the circuit or an internal fault.
Bleed the heating circuit and observe if the buzzing changes before deciding that the motor is faulty.
03
The boiler ignites the burner but does not heat.
Cause: A fault in the motor affects the pump and the valve, leaving both circuits out of service.
Check that the installation valves are open and that there is no fault on the display before replacing the part.
04
There is heating, but the hot water comes out cold or lukewarm.
Cause: If the valve does not switch properly, the motor may operate the heating circuit without prioritizing the domestic hot water.
Check if the fault occurs only when opening a hot water tap, to rule out that it is another component.

Fault codes Saunier Duval that require diagnosis

Code	Fault	Technical checks
F.22	Safety shutdown: lack of water	If the pump motor is blocked/faulty or disconnected (wiring/PCB), there is no circulation and the control interprets a lack of water. Check the pump start in test P.0, presence of PWM/230 V voltage, and motor continuity/consumption.
F.23	Safety shutdown: excessive temperature variation	A pump without flow (blocked or with reduced power) causes an excessive ΔT flow/return. Check the pump's rotation/speed, bleed air, and ΔT in the heat exchanger; verify PWM/230 V control.
F.24	Safety shutdown: temperature rise too fast	If the pump is stopped or performing poorly, the flow rises very quickly as the water does not circulate. Check the power supply and rotation of the pump and bleed the system; if it does not respond in P.0, replace the pump.
F.75	Pump error, lack of water	Upon start-up, the electronics await a pressure variation when the pump starts; if the motor does not turn or does not generate flow, there is no change and F.75 appears. Check the pump test and pressure change, voltage to the pump, and the condition of the impeller.

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.
