Wilo HB16/6.7-2 Circulating Pump Motor for Saunier Duval Thema/Themafast Condens F24
Circulator pump motor manufactured by Wilo, type HB16/6.7-2, identified on the motor label. It circulates the water in the boiler circuit with two speeds: 0.29A/64W and 0.38A/85W. It is replaced when it makes noise, gets blocked, or the boiler ignites but does not heat due to lack of circulation. There is an unresolved conflict between the code printed on the part and the reference published in today's catalog.

How to check if ref. 0020087276 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- 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.
Symptoms and faults that the circulation pump 0020087276 resolves.
The circulation pump circulates the water in the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler turns on but the heat doesn't reach the radiators.
Cause: The pump motor does not move water through the circuit even though the burner is working properly.
Check if the motor speed selector is in the correct position before declaring the pump faulty.
- 02
A continuous noise or a whistling sound is heard in the pump area.
Cause: There may be air trapped in the circuit or wear on the motor shaft.
Bleed the high points of the heating circuit and check if the noise decreases.
- 03
The pump remains stopped and does not start when receiving power.
Cause: The rotor is seized, something common after long periods without use or with water loaded with lime.
Try to manually unlock the shaft with a screwdriver in the front slot of the motor.
- 04
There is a water leak at the pump shaft.
Cause: The mechanical seal that separates the motor from the water in the circuit has deteriorated.
Dry the area and check in the following hours if the dripping reappears at the same spot.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 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.
