You will have to contact the manufacturer for a service manual for your unit. Do you have an access panel. Usually the apron can be removed for easy access. Also, on some units the trim around the switch can be screwed off and the tubing accessed that way.

check for a blocked hose to the pressure switch or a faulty pressure switch
this switch is controlled by water increasing the trapped air pressure on a diaphragm and when the setting on the wash size is reached , it closes of the inlet water solenoid and turns the machine to the next cycle.
if it does move to the next cycle then the solenoid stops on the water hoses are faulty and need to be replaced.

follow this steps .God bless you F/H No water detected entering machine or Pressure switch trip not detected.
If after 30 seconds the control does not detect
water entering machine and then valves will be
turned off and the error code will be displayed. Or If
the control has turned the water valves on and
after 8 minutes the flow meter has detected 10.5
gallons of water passing through it, but has not
detected the pressure switch trip, the valves
will be turned off and the error code will flash. Press PAUSE/CANCEL twice to clear the display.
If there is no water in the unit: 1. Make sure that both valves at the water source(s) are turned on all the way. 2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves 3. Verify inlet valve operation
If there is water in the unit: 1. Verify Drain pump operation 2. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch
Verify there is not a siphon problem
Verify
wire harness connections to:Inlet Valves,
Pressure Switch, Drain Pump, Flow Meter, and
Central Control Unit (CCU)
Check the pressure switch and hose. Pressure switch is what turns the pump on and off. Trouble is usually in the hose so check it first. Look for the hose to be unattached or clogged.
Lid off, right side circular pressure switch with black hose attached. Remove end of hose, blow down to make sure not blocked and blow into switch where hose attaches. Should click twice. If doesn't click, faulty pressure switch (replace)
Parts that may be responsible for the problem and that must be inspected or tested are drain system, pressure switch, pump and control panel.
Troubleshooting will start from the drain system.
The drain filter connected to
the pump is the first part to be checked. With Bosch Axxis the drain
filter access is located in the front side at the
bottom. In recent models you need to remove the trim panel at
the base and you find the access cap. Older Bosch have a door in a
corner. Behind the cover or panel you find a cap that can be released turning
anticlockwise. Before starting disconnect power and keep a container
ready to collect a good amount of water.
The drain hose at the back must also be
checked to make sure that there is no blockage and that the hose height is
set according to manual for the specific model. If the hose is set incorrectly the water will flow back
from the drain hose into the tub, drain will not end and the machine will not advance to spin.
After
checking the drain system inspect the pressure switch. The pressure
switch is the device that detects the water level, when the switch is faulty the machine often does not drain or spin. The
switch is located in the control assembly, near to the timer. To access
the switch the machine must be partially disassembled. The pressure
switch looks like a plastic disk with three or four electrical
connectors. The switch is connected to a long thin rubber hose that
extends inside the tub. Before replacing the switch try cleaning the
rubber hose and the switch nozzle. Excess of detergent may clog the
switch, causing malfunction that often affect the drain and spin part of
the cycle. The switch is not an expensive part and it is difficult to
test. The switch is tested reading Ohms ( or Volts) at its terminals
with tub full and empty. Testing must be done by a trained technician.
If cleaning the rubber hose does not do the job I suggest replacing the
switch.
If the drain system and pressure switch are fine the next
step usually consists in checking pump and eventually replacing the control module if pump and all the rest mentioned above are OK. Before
replacement the module should be tested reading volts during cycle or checking test points in service manual.
If the machine is a built in model it must
be moved out from its housing. The instruction to mount or remove
machine from housing are illustrated either in the owners manual or in
the installation manual provided with the owners manual.
Checkup of the drain filter and drain hose are operations that can be performed by the user. Cleaning the pressure switch hose is not a difficult operation, but requires partial disassembling and must still be performed by a technician. Testing of pressure pump and control panel should be definitively done by a technician.The parts that fail more often when there is no drain or spin are drain system or pressure switch. If the machine is running through the cycle and there is no error code the problem is unlikely pump or control panel.
Start performing the user level operation detailed at start of my comment. Remember to disconnect power before performing any maintenance operation. If you need to call a technician ring the number listed on the owner manual.
You should never try a pump without it being in fuel. It uses fuel for lubrication when it is running. If the vehicle doesn't start at all when you first crank it over it is not the oil pressure sender. If you just put the pump in you might want to turn the key off and on several times to cycle the pump then try to start it. If it doesn't start then check fuel filter or check fuel pressure at fuel rail in engine compartment. Is fuel pump cycling at all when the key is turned on? There is a problem with ignition switches on some of these blazers.
The FH code indicates a problem with the incoming water. Press Pause/Cancel twice to clear the error. It could be water not coming into the washer or the water doesn't reach the desired level after 8 minutes of incoming water.
First check that your water valves are open and that the hoses aren't kinked. Next make sure that the incoming water isn't being siphoned directly into the drain. (This happens when the outlet hose is positioned in the drain stack to be lower than the water level of the washer.)
Turn off the water valves and disconnect the water hoses. Check if the incoming water filters are clogged. Also check that the hoses are undamaged. There are some anti-flood hoses that seal themselves if they detect a leak. Replace the hoses if you suspect this problem.
The next things to check are the inlet valve and the pressure switch hose. This needs to be connected to the tub and the pressure switch. Check that the wiring between several parts (the inlet valve, pressure switch, drain pump and flow meter) and the central control unit. Next check the pressure switch and the flow meter themselves. Also check the CCU unit.
The washer's pump unit has stopped working. It may not me getting the signal to pump after the wash cycle (controller problem) or the pump has let go and needs to be replaced.
