How to lengthen the water supply hoses. There to short to reach sink.

Buy a flexible braided hose for mains pressure. They come in different lengths.

Fit one end to the water outlet tap and for the other end you will need a fitting you can attach the dishwasher hose to that any plumbing supply has. I don't think you can buy a flexible braided hose that will fit to your water supply tap on one end and then straight to the end of the dishwasher hose on the other. You will need the adapter between the 2 to hook the fittings up. Use plumbers tape on the fittings when installing them for a good water seal.

Or you can just get a plumber in who will fit everything up for you and will also probably use a flexible hose to plumb in the water supply.

Clear rubber hose is off machine-what does it do? I've lost the owner's manual and cannot remember how to use the electric washer. Does that short clear rubber hose with a fine filter on one end...

The clear hose with a filter on the end is a cleaning solution pick-up tube. It attaches to the washer near where the pressure hose attaches to the machine. There is ususally a barbed hose fitting for it to slip over. If you are using the black, low pressure, soap tip the hose will allow the machine to pick up cleaning solution either from a bucket or straight from the bottle, mix it in the water and spray it out on whatever you are cleaning. It will not work if you have one of the high pressure tips on the wand. They are usually red, yellow, white or green.

The cold water takes almost an hour to fill the machine. The hot water fills just fine.

shut off water and check screen filters on each end of the hose.
solenoid may be damaged

My kenmore elite keeps showing f20 near the end of my wash cycle

f20 can be your fill a fill hose problem, flowmeter problem.
But first i want you to check you hoses
turn the water off
take the hoses off the back of the washer
get a bucket
put the hoses in the bucket
turn the water back at a time so that you don't get blasted with water.
Do both hot/cold come out with good pressure?
If yes try
take your lid off the washer between the inlet valve and your dispenser is there a white plastic piece one end going to the valve and one to the dispenser.
IF yes take it off and blow through it.
put back on and see if the code comes back
If yes
Then it is possible you may have a bad pressure switch.
let me know how it goes
if you take the kick panel off by removeing the t15 torx screws you will find the tech sheet to help you

I own i 20 gal. clarke abrasive blaster. My problem is that i can only blast for about 30 seconds and then have to wait almost 2 minutes for the pressure to build back up

Sounds like your compressor doesn't have the cfm to keep up with the blaster. Blasters use a lot of air. The cfm of your compressor should match or exceed the cfm of the baster. Try a bigger compressor.
Good Luck!

Water over flows think its the water sensor

It's likely just the hose to the pressure (water level) switch that has come loose or fallen off. Remove the console screws and flip back the console to get access to the pressure switch and the connections. If the connection end of the pressure switch hose looks "stretched", trim 1/4" off and re-seat it.
If the hose looks ok (no cracks or splits), check the other end of the hose which connects to the side of the tub.
The see if the pressure switch is faulty, remove the pressure switch hose and attach a small hose to the pressure switch. Blow into it gently and listen for "clicking". Test with a fill to see if the switch shuts off the water valve.

Let me know if you need more assistance. If so, please post your model number.
Good luck!

Hi , my Karcher water blaster makes a horrible repetitive surging noise when its powered on but not when its actualy blasting. I suspect its the pump bypassing. Pressure is also down on what it used to...

Is there dribbling water coming out of the casing if you plug in the incoming hose but don't switch it on? This is usually the case. Either the seals have worn on the pistons (usually 3) or you have a cracked pump casing.
