It appears your Pressure Switch has failed in this instance.

For replacement parts - head on over to or and enter in your full model number for a full parts listing.
I recommend both sites because ...

FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.

If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.

Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

As it takes on water it overfills and leaks out of the drawer. An earlier answer suggests it is the pressure system. What is this and how do i fix it?

The pressure system you refer to, is the water level switch and pressure chamber, the small hose leading to the pressure switch can get blocked and cause the washer to overfill.
To check the hose, remove the lower rear panel of washer, at the bottom right you will see a large black hose, attached to this is the pressure chamber hose leading to the pressure switch.
Remove the small plastic hose and check for blockage here and in the black hose where the small hose is fastened too.
If it still overfills, then could be a faulty water level switch..

Bolens MTD push mower with B&S 4.5HP 10H902-0285-E1 (SN-03122354).. Runs rough (pulsing) after cutting on an incline where mower was tipped to the right (carb) side.. It seems as if oil leaked over...

This is probably not a blown gasket issue. A bad head gasket can allow oil to enter the cylinder head/combustion chamber if it's not sealing off the valve area. A simple suggestion is to check on the engine opposite the carb side for the oil/crankcase breather. It will have 2 screws holding it onto the block. It has a type of filter media in it that traps excessive oil and oil vapors from the engine. It is also connected by a tube to the air filter housing. When you tipped, you probably put too much oil in the breather and it was inducted over to the air filter/carb intake side.
Clean or replace the breather after checking it and also make sure you haven't overfilled the Briggs with oil and only use SAE 30 in the engine. Muti-viscosity isn't recommended in summer unless you run synthetic, then it is OK.
Please vote on this solution.

Machine doesn't spin properly, drum goes round but only slowly

It could just be the load is out of balance which would mean redistributing the load or adding something if you only have one or two items in the drum. The other scenario is the pressure chamber has blocked and the machine thinks the drum is still full of water. To find out if it is the pressure chamber remove the lid off the machine, locate the pressure switch, it will probably be round in shape and about 3 inches across with a few wires comeing out one side and a rubber hose connected to the under side. Remove this hose carefully and listen for a click as you do so, if the chamber is blocked you will hear the click because the switch is resetting. Now follow the hose down and it will lead you to the chamber, remove it and clean it out, dont be tempted to just blow down the pipe because that is not a lasting solution and will block again in no time. Before putting your hands in the machine turn off the power and remove the mains plug.

It may clear from time to time allowing for the occasional instance when it would spin as normal. The only real way to clear the blockage is to remove the chamber and wash it out under running water, although there are those that say ‘just blow down the air hose’ Believe me this is only a temporary solution because the fault will return. On the other hand it could be the switch is faulty in which case you will need a new one.
The pressure chamber is located under the machine at the rear and will need to be removed from the tub to be cleaned.(you never stated which model you have) so I can only assume it is a split tub type. If in doubt locate the switch by removing the lid of the machine and it is (a round object about 3” across with wires on one side and a small bore air hose underneath).Follow the hose down to the pressure chamber.

Washing machine fills with water but wont shut off

If the water continues to come in without the washer being on, then you have faulty inlet valve, replace.
If it stops when you turn m/c off, then you probably have a sticking water level switch, or a blocked pressure chamber and /or pressure hose.
the pressure chamber and hose are located at the rear right side of the m/c .
Remove lower rear panel, and remove the hose with the long thin hose attached to it this is the pressure chamber and hose, thoroughly clean and fit back.Test it for leaks.
This should solve the problem.
While in the back I would suggest you remove large black hose and clean the filter located in there as this could also be a factor in it overfilling.
Plz rate my solution.

Hotpoint aquarious hault code

fault can be due to more than one cause. take top off machine locate pressurestat - usually a round device with anything from 3 to 7 wires to it and a small diameter tube to it. check no split or crack in tube and that it is not blocked. the small diameter hose goes to an air chamber. often this air chamber gets clogged especially if you use liquid detergent. if clogged, clear it with hot water. pressurestat may also be faulty but these are a reliable device. to test, remove small dia tube and attach your own tube. with machine in fill mode, blow into tube and you should hear a click and water stops ps i live near truro
