A dishwasher that will not take in water can be held up by something upstream or by a safety interlock: the supply valve under the sink is shut, the door is not latched, Control Lock or Delay Start is holding the cycle, or the overfill float is stuck up. Whirlpool, GE, Samsung and LG all publish those owner checks. Past them, the documented suspects are the water inlet valve and its screen, the float switch, the door switch and wiring, and the control.
Still dry after the checks below? Call Plug Fix Repair at (832) 598-8646 with the brand, model number and any display code – an LG IE or Samsung 4C means something different from a Bosch E15 or E24.

From manufacturer owner guidance - no panels, no tools: Sink supply valve.
From manufacturer owner guidance – no panels, no tools:
Safety: the inlet valve, float switch and door switch sit behind panels near water and 120-volt power. Whirlpool says newer models with filling difficulty should be inspected by a professional.
The cycle starts and the machine sounds normal, but the tub stays dry; LG models may show IE and Samsung models 4C.
LG defines IE as too little water in the tub within 30 seconds to 10 minutes and points to closed valves and kinked, pinched or torn hoses. Samsung Canada’s 4C article gives three steps: valve not closed, no kinks, and foreign matter cleaned from the water valve. iFixit adds that under 20 psi can make the inlet valve malfunction.
We confirm flow and pressure at the stop valve, then trace the supply line to the dishwasher, since a hidden kink stops flow as surely as a closed valve.
You hear a hum when the fill should begin, yet no water arrives – the “isn’t dispensing water” complaint in its plainest form.
iFixit says a hum with no water flowing suggests a stuck valve, that a valve can receive proper voltage and still not work, and that the inlet screen can clog with mineral deposits. Whirlpool’s own article says that if there is no obvious blockage at the valve, the cause may be electrical or mechanical and a professional should look.
With water and power off we inspect and clear the screen, then check the coil against iFixit’s 500-1,500 ohm range and confirm the valve receives line voltage during fill.
The float moves when you lift it, yet the machine still acts as if the tub were full – sometimes with OE, oE or OC on the display.
GE explains that the flood float exists to prevent overfilling, and if stuck it keeps water out. iFixit says a switch that fails in the up position stops filling and can trigger those over-full codes, and that sediment in the float chamber makes the float stick.
We check whether the float actually moves the switch underneath, meter the switch in both positions, and clean or replace the chamber if residue is the reason it sticks.
The door feels shut, but START/RESUME keeps flashing, or the panel barely responds.
Whirlpool notes many models refuse to operate unless the door is securely latched. According to iFixit, a failed door switch leaves the machine unable to fill and probably showing no signs of life; it also describes door wiring harness failures on Samsung dishwashers that can affect the door switch and possibly the inlet valve.
We test the latch switches for continuity, as iFixit’s general guide recommends, and inspect the harness where it flexes through the hinge before ordering a latch.
Supply, valve, float and door all test good, but the valve never gets power at the start of a cycle.
iFixit calls a main control board failure a final and unlikely possibility, relevant when the valve receives no power. Its general guide lists testing the timer and electronic control under low water pressure, and GE’s turn-to-start note shows how a mechanical timer can skip the fill entirely.
A control is judged last, and only after we measure no voltage reaching a valve that is otherwise good.
Appointments are usually available same-day or next-day, depending on technician availability and your location. For same-day service we normally provide a 2–3 hour arrival window and call you about 20–30 minutes before the technician arrives.
Bosch : E16 and E17 mean water may not be able to enter - check the inlet hose for kinks or damage. LG : IE means insufficient water; if it persists with both the supply valve and water pipe valve open, LG says to contact the installing technician. Samsung : Samsung Canada lists 4C or 4E as a water supply error and says to avoid FloodSafe hoses; OC, 0C or oE is over-level. GE : most 2015 and newer models have an owne

Same-day appointments come with a 2-3 hour arrival window and a call about 20-30 minutes before the technician arrives. Phone (832) 598-8646, Monday-Saturday, 7:00 AM-7:00 PM; near the edge of this map, we confirm availability based on your ZIP code. More on our dishwasher repair page.
