I would tend to disagree that the hose came off the pressure switch. I am guessing that your correct model number is LCR5232dq2, which is a "World Washer" portable washer made by Whirlpool. Access to the workings of this type of machine isn't very easy. You take off the 3 or 4 screws along the back that hold the top to the cabinet, about at the level of where the power cord enters the machine. You can then pull up on the back of the top, and slide the top forward to free it from the cabinet. There are a number of electrical and hose connections that reduce the ability to flip up the top and see everything. If you are brave, you can disconnect things if you need more access.
The reason that the hose probably didn't come off the switch is that there are actually 2 hoses: a short one that goes from the switch to the cover that shields the controls, and a long one that goes from the cover to the outer tub. The former probably isn't your problem; check the latter for chafing or breakage, or if it came off the cover, or broke the nipple where it connects to the cover itself. You should be able to see a visible sign of a problem with the hose.
On the other hand, if your washer fills even if you turn the machine off, then you have a problem with the fill valve itself.
