The switch does not stay down on my RHOK3123, and therefore it will not stay on. When I hold it down it works perfectly.

sounds like u need to replace the on / off switch the start switch is defective

see pics

Try this to fix it

look and see if the Kill wire is hooked in wrong spot on linkage therefore grounding it out when you squeeze handle

buttons are not working perfect.therefore pressing automatically. you have to remove the panel after power on the monitor, (it may be dangers therefore get support by electronic technician , he will remove buttons and solder new ones or replace the switch panel.

The switch is operated on what is called a thermocouple - the most lightly problem is lime scale. Get some limescale remover from your local hardware. or you can use spirit vinegar and boil the kettle a couple of times. Give it a really good clean afterward or your coffee will taste awful! Good luck.

this is more likley to be the switch its just a bimetallic type,when it gets hot steem on it it flicks the switch to turn the kettle off try giving it a realy good clean up inside around the switch it may just be lime scale blocking the vent hole
however normaly when the switch playes up its a new kettle

Pull the wand out of the Vac. Need to use a small Torx bit to take out 2 screws hidden behind the wand storage. Once screws are out, there are 4 push-clips which need to be un-latched. Pry the power panel off and you will expose the two switches (one for power, one for the brushes). Push the power switch down and it should "release" and go back to clicking when pushed. Re-assemble. Took about 5 minutes to fix.

Look under the kettle at the round circular connector in the bottom. Inside there is a small button that is depressed when the kettle is put on the base. If this is not pushed in far enough it will have problems.

The cause is that after some use the connector in the base plate collapses into the base by 1-2 mm This means the switch is not pushed in far enough.

My kettle had similar issues... I pulled the base plate apart (3 screws I think) and cut a round disk of plastic to lift the connector up by about 1-2mm and then reassembled the base.. No more issues
