Grundfos Circulating Pump UP 15-60 A0 For Saunier Duval Themafast F24E - Ref. 0020087276
Circulating pump motor Grundfos, model UP 15-60 A0. It moves water through the circuit of the Saunier Duval Themafast/Thema Condens boiler. Replacement requires first confirming the fault of the part through technical diagnosis, even when it does not start, makes noise, leaks, or the impeller is blocked after a period of inactivity. Actual manufacturer is Grundfos, different from the commercial brand of the boiler.

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.
Symptoms that require diagnosis in the circulation pump 0020087276
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 is not heating or is heating poorly.
Cause: The pump is blocked and is not pushing water to the heating circuit.
Check if the pump vibrates or hums when the heating is turned on; if it doesn't transmit anything, it may be blocked.
- 02
Noise in the pump motor
Cause: Air in the circuit or low pressure generates that noise in the motor.
Check the pressure gauge of the boiler and bleed the air from the system before replacing the pump.
- 03
Water leak from the pump body
Cause: The gasket or the internal mechanical seal has lost tightness.
Dry the area and check if the leak reappears after a cycle of operation, before declaring the pump as lost.
- 04
Pump that won't start after a period of inactivity
Cause: The rotor gets stuck due to prolonged inactivity, which is typical when resuming heating after the summer.
Try to manually free the shaft through the front slot of the motor before replacing it.
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.
