Is there a reset button on the karcher de 4002

Short circuit inside machine. In a device typically resulting from the unintended contact of components and consequent accidental diversion of the current.

If you contact one of the Karcher Centers ( details are on Karcher.co.uk website) they may be able to help.
regards Gary

there should be a labeled fill line on the clean water resavore

this machine uses an electrical solenoid to open the flow of steam from the heater..... the switch is in the hand trigger and the valve on the machine.... one of these is at fault

If you have a Karcher then you should always post your machines barcode.
The karcher barcode is on a silver sticker and is usually 15 digits long. Example 156987400000123 is actually model 1.569-874.0 and serial number 00123....

Owners Manual For Karcher DE4002 Steam Cleaner

My Karcher K 3.99 is leaking and dropped pressure. is it fixable (not filter)

I know that Karchers steam cleaners have had issues with the thermal overload. I have repaired Karcher machines that got turned on with no to little water in the tank and it would heat up really fast and trip the thermal overload. The thermal overload is to reset it self when it cools down but the problem has been the thermal overloads get stuck and dont reset. When they stick, they will give the same signs you have said. In those cases the thermal overload has needed replaced. The thermal overload did its job to trip, but it fails when reseting. I understand you don't want to throw more money into it, but that is the only thing you can do. You can get the part and do it your self, but they are tricky machines to get into and you dont want to break something trying to get in. Hope this helped.

there was a techinal update on this machine a few months ago, the oil may be leaking from the swash plate housing
