If an error occurs, one of these messages might appear. Here's what they all mean:

Before payment is authorised:

‘Invalid code’ means the app didn't recognise the scanned QR code or the typed numeric code. What you can do:

• check GPS is enabled and try again
• pay in the shop instead 

‘Technical Issue’ could mean there was an error with the system that runs Pay at Pump

• you can either try again
• or choose to pay in the shop - you’ll need to get the pump manually authorised by the Customer Assistant before filling up. 

‘PayPal Wallet Issue’ - the authorisation process was rejected by PayPal:

• try authorising again
• or pay in the shop
• if you pay at the shop, you’ll need to get the pump manually authorised by the Customer Assistant before filling up
• you can also contact PayPal about your account authorisation.

After payment is authorised:

‘Time out’ - the pump wasn't started in time:

• you can try again
• or choose to pay in the shop

‘Cancel by Site’ - the Customer Assistant cancelled the transaction:

• they’ll let you know a reason for the cancelled transaction, before manually authorising the pump
• you can then pay for your fuel in the shop when you’re finished
