Hotpoint ADP 4501/5. Machine switches on (ie the lights come on) but nothing happens when you try to run any program and there is a pool of water at the bottom of the inside of the machine which hasn't drained away.

    Sorry this is a Whirlpool dishwasher, not hotpoint

    Outlet pipe appears to be clear, could there be a blockage inside the machine which I could access by taking the backing off?

    If there is a drain issue, sometimes there is an obvious
    Check the drain hose for any kinks, as well as checking any lint
    filters in or on the drain hose. Is there a lint sock on the end that's
    full? Perhaps the drain line itself is plugged. You will want to make
    sure that the house drain system is not backed up or plugged. Always
    make sure that the washer drain hose is above the level of water in the
    drain tub. Some Whirlpool/Kenmore washers make use of a side-check
    valve near the tub outlet which may get clogged. A standpipe should be
    at least 1 1/4 inches in diameter, and never seal a drain hose into a
    standpipe. This can lead to back-siphoning. You also want to make sure
    that the standpipe is less than 96 inches in height.

    Pump problems show various symptoms. Sometimes the pump will
    lock up
    and seize. If the motor is running, it will continue to try to turn the
    pump. In the case of belt-driven pumps, the belt may break or burn
    through. The pulley may shear off. If there is enough tension on the
    belt, and the motor continues to try to turn it, you may wind up with a
    seized motor as well. The pump itself may have seized bearings, be
    jammed by clothing or another object; or the impeller blades may be
    broken off. The usual fix is to replace the pump.

    If you think your pump may be jammed, drain out your tub and
    the hoses. Look inside the hoses and see if there are any obstructions.
    Feel around inside the pump inlets for anything that may be jamming the
    pump itself. You can also use long-nosed pliers to feel around inside
    the pump for any items that may be causing a jam. If you haven't found
    a jam, and you still believe there may be a jam in the pump, you can
    completely remove the pump from the washer and inspect it more closely.

    Occasionally, transmission gears may become worn, or some
    internal part may go bad. Some older washer models have an
    electric-mechanical shifter. If it won't shift, it's best to call a
    professional appliance repair person to address this issue. If your
    transmission is leaking oil, there are really only two options at this
    point, either run it until it dies completely, or replace it now.

Hotpoint H2O error

Please check on the water flow to the drum, if the flow is low or if the inlet is choked the water flow in the set time limit can be low and so could trip.
secondly it can be due to problems in the level sensor, try and see if the pressure switch works outside.
Finally check on the program controller unit once again to see the triping. check the door switch for loose connection.

Power light and extra rinse rapidly flashing

Sounds like a cold water supply fault which could be the solinoid valve, the water turned off, a kinked or twisted cold supply pipe or a wiring fault. Check out the error code sequence here. You never said what make or model you have (the error codes are only for Hotpoint, Creda and Indesit machines)

How to reset whirlpool dishwasher adp4501/5

whirlpool dishwasher problem adp 4501 - I had a problem with this machine not starting properly, hunting, with the start light flashing apparently continuously the pump also going on and off in time with the flashing.
After looking around a number of forums I cleaned out the sump gently with a sponge which did not help, then followed this up by pouring a kettle of boiling water into it. This had no immediate effect, but after a few hours the machine started and ran properly again.
Cost no money and saved me the hassle of taking it out and stripping it down - well worth a try.
