The E020 error is not listed in the provided error codes, so its exact meaning is unclear. However, based on the context, if the Schaudt LT 632 B display does not light up when connected to 220V after replacing a low voltage battery, possible issues include:

1. The leisure battery may still be deeply discharged or damaged.
2. The 230V mains connection may not be supplying power.
3. The EBL (electroblock) may not be charging the battery or distributing power.
4. A fuse may be blown, preventing power from reaching the display or control unit.
5. The system may have shut down due to undervoltage protection.

It is recommended to check battery voltage (off-load), confirm 230V supply, and inspect fuses and connections.
