LF error code

Hello
The LF error code is : NO WATER DETECTED ENTERING WASHER OR PRESSURE SWITCH TRIP NOT DETECTED. Possible Causes/Procedure
1) Check if the home has low water pressure; open the water faucets
2) Unplug washer or disconnect power.
3) Make sure that cold and hot valves at the water source(s) are turned on all the way.
4) Check for plugged or kinked inlet hoses or plugged screens in the inlet valves.
5) Check all hoses for possible leaks.
6) Check if the customer used an aftermarket “no flood” hose. This can sometimes
stop the flow of water to the washer.
7) Make sure that wire harness connections from Inlet Valves (double and single),
Drain Pump, Pressure Switch, & CCU (PR6, DP2, VCH7, and DI6 cavities connectors)
are not broken or with wires detached, and that connector internal pins are visible.
8) Check the continuity between the following components:
A. Inlet valve connectors (double and single) to the CCU (VCH7 and DI6 cavities)
B. Drain Pump & CCU (DP2 cavity) connectors
C. Pressure Switch & CCU (PR6 cavity) connectors.
9) If the continuity diagnosis failed, Main Harness must be replaced.
10) Check the resistance of the Inlet valve in each port of the valve (double & single).
11) Make continuity test to the Pressure SW. See page 7.
12) Verify that the pressure switch hose is in good condition and properly connected
to tub and pressure switch.
13) Check hose for possible leaks. Remove hose from pressure switch. Make sure
that the open part where the hose is connected doesn’t have debris.
14) Check pressure switch operation. Remove pressure switch. Blowing air through
the opening, the two internal switches are heard one by one.
15) Check for Suds.
16) Verify there is not a siphon problem.
17) Make sure that all the connectors are fully seated.
18) Plug in washer or reconnect power.
– If still not functioning properly , verify the washer operation by running the Diagnostic Test cycle.
