Breville Dual Boiler Espresso Machine (Needs Repair)

BDB for parts or repair. 900 model. Has a new pump, solenoid, stainless steel dispersion screen and new silicone gasket also comes with old gasket which is also fine. Issue started intermittently where it wouldn't get up to temperature and go in the ready to brew state. Sometimes it worked sometimes it shows a too high temperature but doesn't actually seem like its that hot so it's likely an electronic or sensor issue. I tried cleaning off some of the temp probes. I have also donated one of the little c clips on the steam boiler to another machine I was trying to repair. So it needs that first before starting it up and trying again.
