I have a Bosch TES 503 coffee machine which keeps asking us

Customer Question

I have a Bosch TES 503 coffee machine which keeps asking us to run the decalc program - even minutes after we have completed a decalc procedure. It doesn't seem to register that we have done even though it has stepped through all the procedure itself. Is there some way to reset this machine or otherwise fix it?

Thanks for counting on us to help with your appliance problem. My name is ***** ***** I look forward to helping you! Page 86 in the service manual available below shows how to clear and restore factory default to the memory. Let me know if that does not reset the error.
