You need to refresh the page if you try to increase your card balance to a value over 60 €. The maximum card balance is 60 €.
At a mensa checkout desk

Troubleshooting
The balance is limited to 60€. If you try to add more money, the process will fail.
After the card balance has been increased, the new balance will be credited when the card is next used. Sometimes it is necessary to manually check the card account balance (see next question) in order to synchronize the new balance.
How to check my card account balance?
Hold your card on to the card reader of a reload station or washing payment machine without clicking anything on the touchscreen. If you added money online, this can help to synchronize the new card balance.
