did you find out how to sort the strobe 31 error or what it even is thx davidWell tubes checked and cleaned and connectors double checked.
Now the annoying strobe error keeps coming up.
Can't seem to put the machine into test mode ! switch on press and hold green button but no indication or result from pressing any of then buttons. Do you need to hold it down for a long time or as you switch on and then close door ?. If it does not go into test mode can't test the solenoid on the tubes.
Any idea what the strobe error 31 is ?
cheers all
