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.

Look at the motor label: it should say Grundfos UPS15-60 RLE and the code 8716771386 or the P/N 59806402.
Compare the power ratings: this one indicates 45, 75, and 95 W. If yours shows different figures, it is not the same pump.
If your pump has 8716771302 (pump) or 8716771427 (motor) in the Euromaxx spare parts list (copy from a third party), send us a photo: this unit has 8716771386 and we will compare them.
If your boiler is the Junkers ZWC 28-1 MFA 31, it is already confirmed. Any other model or questions? Send us a photo of your pump's label and the boiler's PCB from the Contact section.

Diagnosis and fault codes

Symptoms that require diagnosis in the junkers

Common symptoms and faults

01
The radiators do not heat up even though the boiler turns on.
Cause: Bleed the radiators and check that the pump is running before replacing it.
02
The pump hums but does not rotate.
Cause: The rotor may be stuck after a period of inactivity: have a technician try to unlock it before replacing it.
03
Noise or vibration in the pump area.
Cause: There may be air or low pressure in the circuit: check the pressure gauge and bleed.
04
It is leaking between the motor and the pump body.
Cause: Check if the water is coming from the pump or from a nearby gasket.
05
The boiler locks out due to overheating.
Cause: There may be a circulation issue: check that the pump starts and that there is no air in the circuit.

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.

Pending applications to verify: • ZWC 28-1 MFA 31 (noted by the warehouse; the official manual writes ZWC 28-1 MF2A 31): 1 source (“ZWC24/28-1MFA31”, ref. 8716771427). CONFLICT: the official manual states that the pump for this boiler is 100/130/150 W, not 45/75/95 W as the label indicates, and does not name it. • ZWC 24-1 MFA 31: 1 source (“ZWC24/28-1MFA31”, ref. 8716771427). • ZWC 28/32-1 MFA 23 and ZWSE 35-6 MFA 23: 1 source (ref. 8716771427). • ZWC 24-1 MF2A 23: 1 source (breakdown of: “WATER PUMP MOTOR ZWC28”, ref. 8716771427; does not name the pump model). • ZWC 24-1 MFA 23: 1 source (P/N 59806402, REF 8716771386). • Cerapur (family, without model): 1 source. • NGVM24-5 and the Euromaxx without gas year mentioned in the Uniclima FAQ: valid.
Registered equivalents and substitutions: There is no documented equivalence between 8716771427 and 8716771386 / 59806402 from the label: only Uniclima claims it, which is not valid. For P/N 59806402, it provides two REF: 8716771386 and 8716771387. It states that 8716771427 is listed on the motor label (the same phrase appears in other technical sheets); this unit carries 8716771386. No documented substitutions.

Before purchasing

To confirm: ZWC 24-1 MFA 23, with the P/N from the label.
To confirm: ZWC 24-1 MFA 31 — (possible common catalog) they list it with reference 8716771427 and not with the one on the label, model ZWC24/28-1MFA31 (it is written ZWC24281MFA31). Including 24-1 MFA 31 is a deduction from the notation 24/28.
To confirm: ZWC 28/32-1 MFA 23 — The same ones (possible common catalog), with reference 8716771427, not with the one on the label.
To confirm: ZWSE 35-6 MFA 23 — The same ones (possible common catalog), with reference 8716771427, not with the one on the label.
To confirm: ZWC 24-1 MF2A 23, with reference 8716771427 (Euromaxx table, copied from a third party, which does not distinguish between 23 and 31); it does not mention the pump model.
To confirm: Cerapur; it does not indicate the boiler model.
To confirm: Euromaxx ZC 24-1 MFA and ZC 28-1 MFA — with reference 8716771427 (Euromaxx list, third-party copy); none provide the models.
Do not confuse: UPS 15-60 130 (96281478) — UPS 15-60 from the general catalog of Grundfos — Another P/N: it is not 59806402.
Do not confuse: 59526609 (UPS15-60 130 mm) — Another UPS15-60 from Grundfos — Another P/N: it is not the 59806402.
Do not confuse: 8716771596 — Pump motor casing (pos. 1 of group 5.1 of the Euromaxx spare parts list) — It is the casing, not the pump.
Do not confuse: 8716771264 — Diverter valve body (pos. 6 of the same group) — It is not the pump.
Confirmed for the Junkers ZWC 28-1 MFA 31. The Euromaxx spare parts lists (third-party copies) provide 8716771302 (pump) and 8716771427 (motor); only 8716771386 from the label, as Junkers pump.

Frequently Asked Questions

Frequently asked questions: junkers

Is it suitable for my boiler?

Yes, if it is the Junkers ZWC 28-1 MFA 31: Confirmed: for it. For other models, we have not confirmed it yet. Send us a photo of your boiler's PCB and the label of your pump from Contact and we will check it.

Is it the same pump as the 8716771302 or the 8716771427 from the spare parts list?

It is not confirmed that it is the same pump. A third-party copy of the spare parts list Euromaxx 6720611197 shows 8 716 771 302 0 as the pump (pos. 30) and 8 716 771 427 0 as the motor (pos. 3); (possible common catalog) they sell the 8716771427 as UPS15-60 RLE. Without additional confirmation, it links it to the 8716771386 from this label. If your pump has another one of those codes, send us a photo and we will compare them.

Is the pump of the ZWC 28-1 MFA 31?

Yes. Confirmed: for that boiler (it is listed in its official manual as ZWC 28-1 MF2A 31). The copy of the manual describes a 3-stage circulation pump and does not provide its model.

How many speeds does it have?

Three: 45 W, 75 W, and 95 W, according to the label.

What do the codes on the label mean?

To confirm: 8716771386 is the Junkers (Bosch) code and 59806402 is the P/N of Grundfos for the UPS15-60 RLE. The part also carries the code 0423JUN. List 8 716 771 386 as Junkers pump, without boiler.

Who should install it?

A qualified technician: the pump operates at 230 V and is part of the heating circuit of the boiler.

What other boilers use a UPS15-60 RLE from Junkers?

only the ZWC 28-1 MFA 31 has been confirmed. (possible common catalog) they sell a UPS15-60 RLE with reference 8716771427 for ZWC24/28-1MFA31 (: ZWC24281MFA31), ZWC28/32-1MFA23, and ZWSE35-6MFA23, but none mention 8716771386 or 59806402. Compare your pump code with that on this label.
