Customs data, HS Code and country of origin
The data relating to HS Code, customs code and country of origin, when present, is indicative and does not constitute customs advice. It is reported based on the information available when the product page was created, provided by the manufacturer or found on the product/packaging. This data may change. For specific customs requirements or absolute certainty, we recommend contacting us before purchase.
Product packaging
As we sell spare parts and accessories for household appliances, many items are supplied loose by manufacturers, without printed or dedicated packaging. When original or specific packaging is present, it is normally visible in the item photos. Otherwise, the product may be supplied in neutral packaging or without retail packaging, always with suitable protection for transport.
Item dimensions and measurements
The measurements shown on the product page are taken when the item is created and may have a small indicative tolerance of about 1-3 mm. Compatibility should mainly be checked through the brand and model indicated in the description. If the spare part is purchased for models not included in the compatibility list, we cannot guarantee correct fitting based on measurements alone.
Photos, details and technical specifications
The photos and technical specifications are created or reported with care when the product page is created. The manufacturer may change small aesthetic, construction or technical details over time without notice. Any variations do not affect compatibility when the item is purchased for the models indicated in the description. For use on models not listed as compatible, we recommend contacting us before purchase.

Symptoms and Diagnostics (Q&A)
QUESTION: How can I tell if the PCB is really faulty?
ANSWER: To diagnose an electronic board failure, try these steps: first, check that the machine is correctly connected and that the socket is active. Then remove the plug, open the appliance and look for visible burn marks on the board or melted or swollen components. If the coffee machine still does not respond after these checks, the AS00007843 PCB is probably faulty.
Tips and Maintenance
To extend the useful life of your new electronic board, follow these simple precautions:
1. The number one enemy of PCBs is moisture or water: always make sure there are no internal water leaks from the pipes or boiler that could drip onto the circuits.
2. Voltage surges can burn out sensitive components, so it is good practice to use a filtered socket or unplug the machine during severe thunderstorms.
3. Keep your coffee machine and the surrounding area clean: the accumulation of dust or the presence of insects attracted by heat or coffee residue can create unwanted electrical bridges on the electronic board.
