Hi, does anyone know how to turn the preheat off on a glowworm ultra com 30cxi? It’s the one with the 3 round buttons, I’ve tried the - part of the tap button but it just brings it to the water temp setting so totally confused on what to do. Not even sure how it started up - never had it before- so assuming something has been knocked to turn it on - thanks
 
Good afternoo,

My apologies. However I think a lot of them work in the same way, so you could try the things mentioned there, or try taking the temp up to max, then all the way down to minimu, see if that knocks it off.
