Warranty & Repair














Please note:

All ESU products come with a 2 year warranty, valid from the point of sale date.  If purchased through one of our registered Dealers the product must be returned to ourselves through the Dealer from whom you purchased. 

However if purchased direct from ourselves, please contact us prior to return.  (proof of purchased required).



Should there be any reason for complaint about our ESU products, despite substantial quality controls, please feel free to chose between the following possibilities to get a functional article:

Guarantee claims

Of course, there is a statutory two-year period of warranty for all ESU products. This period is valid from the moment you buy a product at your retailers shop. If the product becomes faulty within this period, guarantee claims come into effect. You should contact the retailer from where the product was purchased to discuss your options.

If you have to travel long distances or the retailer is no longer in business ESU offers you to return the article directly to the companies service department in Germany.

Should you assert your guarantee claims directly against ESU, we compulsively need a sales receipt ! or a proof of purchase that clearly shows the exact date of purchase. Please always insist on a properly written invoice when you buy a product and keep it safely for two years. Only with this receipt guarantee claims are assured!

Repairs with costs

It may also be possible to repair an ESU article which is out of the two-year warranty period. In this case please send the article to our service department. Our technicians will check the item and decide if it can be repaired or replaced.

For this special service we generally introduce service charges.

You will receive an invoice for the repaired / replaced items. We do not accept any kind of quotations or an estimate of costs. If there is obviously no case of warranty, service charges will automatically come into effect.

ESU decoders in factory-assembled locomotives (OEM)

Many ESU decoders have already been pre-installed into locomotives that come ex factory. These decoders are exclusively provided with special settings for the respective customer and his locomotive to some extent. The so-called OEM decoders may considerably differ from our ESU standard decoders.

If these decoders shouldn΄t work probably anymore, please refer it DIRECTLY to the manufacturer of the locomotive or to the shop where you purchased the locomotive.

Please never return an OEM decoder or even the whole locomotive to ESU, since we can΄t accept any direct warranty claims for such decoders! All OEM decoders and locos will be sent back unrepaired.


Service Repair

Within 3 years from the date of purchase, we will repair defect ESU products which are no longer covered by warranty.

Prerequisites for this are that faulty products are sent within 3 years after date of purchase and the original proof of purchase (receipt) is enclosed. The repair service only applies to ESU products that are bought from ESU dealers and do not apply to decoders that have been installed ex factory.

For decoders or LokProgrammer devices older than 3 years after date of purchase or without receipt, you are still able get a new ESU product. Check our exchange fees.
