Yes, as wrote by "bridge" you have to replace the vacuum breaker valve.
The steam that come from the spout near the grill, it coming from the vacuum breaker valve that did not seals, so the water temp will remain at the boiling temp, but the heating element will remain powered on continuously.

If with the new vacuum breaker valve the issue persist, probably the SSR is defective.
Maybe the first diagnosis was incorrect, i did not consider that if a SSR is defective it will not heat up the boiler enough to produce enough steam/pressure to make the vacuum breaker valve to seal.
If you can locate the steam boiler SSR, the definitive test could be swap the SSR, so you can verify it without doubt. :wink:

i found a photo from another thread, that is a profitec 700, so the SSR are in the right side of the machine.
You only need to swap the wires, the couple i circled in red are the signal from the PID the couple i circled in blue are the live wire of the heating element, i don't know which one is the SSR of the steam boiler, but should be the SSR that is missed in the photo due to the photo author had problem as well with the steam boiler SSR.
Hoping your machine to back in business asap.
