Question about Garden
Don't know this model intimately but it looks similar to the Karcher which is really total **** nowadays as its all made of plastic. The motor has a weird switch mechanism but if it tries to run and the motor doesn't then 100:1 the motor is seized. Very unlikely it's the actual motor but the pump is a "swash" plate that opens 3 stainless steel thin flat valves. the bearing that the pump shaft goes through is a phospher-bronze plain bush with a seal each side and if this has dried out then you are screwed. Same if you model has steel roller bearings. However, if it does run and build up pressure and it stops because the output pressure is too high then the overload pressure switch is faulty. If it is the Karcher type then again you are stuffed but if it is similar to the Nilfisk then a replacement is available for around £100 GB Pounds - probably cheaper to buy a new one.

Hi and welcome to FixYa I am Kelly. When an electric pressure washer sits for an extended time the residual water inside the pump eventually starts the corrosion process. In as little as 2 or three months enough corrosion can form inside the pump to freeze the pistons in the pump and of course the motor in place. Here is what you can attempt to try and free the pistons. Place the unit on a piece of cardboard and then slowly introduce a light weight oil into the water supply connection. You will need to ensure you add enough oil that you start to notice it at the pressure hose connection. Let this sit overnight on the cardboard.
Next day you need to attempt several rapid off and on sequences (10 at a time less than 1 second each) using the torque of the motor to momentarily make micro movements of the pistons. Let the unit sit for 30 mins if it did not clear and try it again (10 more times rapid on/off cycles) Let it sit another 30 minutes and make the final attempt to get the pump free.
It most likely will free up by doing this but if the interal corrosion / debris is too much your faced with having to physically remove the corrosion by opening the unit and doing repair.

Hello & Welcome to FixYa
This is a common issue with Whirlpool Duet washers however, your whirlpool duet washer can be reset to resolve the control lock problem. Press and hold the END OF CYCLE/CYCLE SIGNAL button for 15 seconds to reset the control. Please get back to me if you have any other questions.
