Recognising and ordering original Bosch parts
An original Bosch part is the part that Bosch itself supplies for the appliance, with the manufacturer part number of Bosch. For Bosch, that is 10 digits, usually starting with 87 of 7736 (for example 8738717111). That number is on the old part, in the exploded view of your model and on every Instalpunt product page (also in the title), so you can compare them one to one.
- Which appliance do I have? Brand, type and year of manufacture are on the rating plate. How to read the rating plate of your Bosch.
- Know the part number? Search directly by manufacturer number or part number in the spare parts catalogue; how to find the right part.
- Original or alternative? When an alternative is possible and when it is not.
- Fault code? View the Bosch fault codes with the cause and the part that is usually replaced.
- Delivery, returns and warranty: stock items: shipping to EU countries from €12.95 (€16.95 for more distant countries), usually 3–5 working days (shipping); made-to-order items are ordered specially for you; the 14-day right of withdrawal applies (returns conditions). All parts carry the manufacturer's warranty of Bosch (warranty). More about the shop: about Instalpunt.
Please note: we do not check whether a part fits your appliance. Compare the manufacturer number with the number on your old part or in the exploded view of your model; if in doubt, check with Bosch or your installer.

Frequently asked questions
Which Bosch spare parts does Instalpunt supply?
Instalpunt supplies 2,886 original parts for 230 Bosch models, including Nefit and Buderus parts, temperature sensors, insulation and O-rings. Each part is listed in the catalogue with part number, price and stock status.
How do I find the right part for my Bosch appliance?
Choose your model above to see the complete parts list (for 125 models with an exploded view). The model type is on the rating plate of the appliance. Already know the part number? Then search by number directly in the spare parts catalogue.
For which Bosch models are parts available?
Among others for the Turbo Tower HRC 30 Solar, TOP 30 400 2 SOLAR, HRC II 30 Turbo Comfortsysteem 65, Turbo Tower HRC II 30 (ZB30150 S-3MA5), HRC II 35 Turbo Comfortsysteem 65, HRC II 30 (ZWBR30) and 224 other models. Is your model not listed? Ask the manufacturer for the correct part number; with that number you can find it using the search function.
Are these original Bosch parts?
Yes. They are original manufacturer parts for Bosch appliances, with the official manufacturer part number. That way you can be sure the part fits and the warranty on your appliance is preserved.
