esl6115 temperature of water?

hi guys need help for a damsel in distress

machine runs through prog , water tepid not hot, is there a stat and is it likely to be saying the temp is up when it isn't, so machine not waiting for heat ?
does the program normally pause while the water is heated.. as it does not at the moment

relay working and 230 v being fed to element cables. haven't checked ohms on element yet.. but slight heat in water, so thinking stat more likely problem.

do you guys know how to test stat if that's likely cause and if it's a mission to replace it, in situ or must i pull machine out for access

apprec. your time, ta
