junkers boiler won't ignite fault code C4?

Junkers boiler zwc28-1 mfza/31 had rain water running through the boiler. Now won't ignite. Have been trying to dry it out for 7 days with a hairdryer underneath. Fault code C4 comes up with no triangle flashing on the front panel. Help what does C4 mean?
