Beko wmb1ow leaking cant see where from

not un common for manufacturers to test every 5th , 3rd , 10 th machine if yours came with a defective/ cut/ or otherwise failed pump to drain hose or tub to pump hose. my 15 years in the business hint noisy in spin points at unseated main tub seal/bearing call for factory service don't void warranty by fiddling with it your self ( maybe an easy fix slipped hose,maybe a 3 hr repair for a qualified journeyman appliance technician.
.

try to dismantle pump and reposition it and clean dirts that have accumulated on it that prevents water to fully drain. best i got

You have a bad pressure switch or the small hose connecting to the pressure switch may be bad

If the washer leaks water when is filling only, check the following: 1.Fill hoses
2.The water mixing valve
3.Filling injector ( If your washer uses one )
4.Filling spout

If the washing machine leaks during the wash cycle, check the following:
1.The pump
2.The tub stem & seal
3.Tub to pump hose
4.The drain hose
5.Tub (rusted holes)
6.The drum support bolts

If the washing machine leaks during the spin cycle, check the following:
1.The drain hose
2.The tub cover seal
3.The pump
4.The pump hoses
5.The stem & seal
6.The drum support bolts

(1) If the washer is leaking water the drain pump might have a hole or crack. Or, the bearings might be worn out. Replace the drain pump if it is leaking water, they're not repairable.
(2) Check the tub seal for tears or cracks.
(3) Check the door boot seal for condition.
(4) Also check the tub-to-pump drain hose for cracks or tears.
(5) Lastly, check the drain hose for condition.
Replace whichever offending part that is found to be defective.

Could be a Tub Seal leak my 1st choice. Could also be a leak caused by a cracked outer tub, issues from the hoses from the drain line connections to the drain pump, drain pump and or drain line.

Are you going to try to DIY the fix?

Drain Pump is the most likely thing. Although could be leaking hose, or cracked tub, or leaking tub seal

You need to remove the front panel to see where the leak is coming from. It could be. Drain Hose or the pump but you will surely see it with the front cover off. http://www.youtube.com/watch?v=vogysB7XOc8

It leaks Your washer can develop several types of leaks. You can track down a leak based on when it occurs: 

During fill only
During drain and spin only
All the time
During fill only If the washer leaks only during the fill cycle, check these:

• Air-gap device -The air gap is a small device found on most washers that prevents the wash water from being siphoned into the household water supply. It's located either mid-way along or at the end of the black rubber hose that comes from the water-inlet valve. Often it's made of translucent plastic. If one of the air-gap components deforms or cracks, you may need to replace it.



• The tube -There's a rubber tube that runs between the water-inlet valve and either the air-gap or the inlet spout. If it cracks or breaks, it can cause a leak.



• Inlet spout -Most washers have a plastic spout near the top of the main clothes tub that directs the water into the tub. If the spout cracks or breaks free of its mounting, it can cause a leak.

During drain and spin only A washer that leaks only during the spin cycle often has a leak in the main drain hose. Inspect the entire hose and correct any problem you find. Alternatively, the steel or plastic outer tubs can rust, split, or be punctured. This may be most visible during large loads and high water levels. If this happens, you may have to replace the entire outer tub--but that may not be an economical repair to make. Consult a qualified appliance repair technician for further details. 

All the time If the washer leaks all the time, check these:

• Hot and cold water fill hoses - Check the hot and cold water hoses from the household plumbing. If either hose is leaking, tighten it or replace it, as appropriate.



• Main tub seal - The main tub seal is located between the transmission and the outer tub. It's the primary water seal in the outer tub for the transmission-shaft entry point. If this seal leaks, you can see the leak by opening up the machine's main access panel while the machine is full of water with a small amount of detergent in it. The leak appears at the underside of the outer tub, at or near the center. This seal is difficult to replace. You probably should call a qualified appliance repair technician.



• Pump - If the pump leaks, you can probably spot the leak when the tub is full of water. The pump has two or more black rubber or plastic hoses attached to it and usually has a drive belt that spins the pump. If the pump is leaking, you need to replace it.



• Outer tub - Over time, the steel or plastic outer tubs can rust, split, or be punctured. If this happens, you may have to replace the entire outer tub--but that may not be an economical repair to make. Consult a qualified appliance repair technician for further details.

CA Cl Average current limit Or Instantaneous current limit If a status signal comes back from the motor controller that a current limit has been breached, the unit will return to standby mode and display either CA for average current limit trip or Cl for instantaneous current limit trip.
Average current trip occurs if there is a 2 second average of current draw greater than 5.55 amps at the motor windings.
Instantaneous current trip occurs if there is a spike of 26 amps instantly at the motor windings.
This may signify problems with the drive motor, thermal protector, or motor controller. Over-loading the unit may cause this problem.

Need to check drain pump and its hose connections. If its not from the drum seal then that's usually where the leaks occur.

Sounds like my 91 Geo Merto LOL! Anywho when it washes the pump spins one way and water is basically thrown back into the tub, then when on spin it spins in the opposite direction and if there is a hose leak past the pump or the pump itself leaks it will come out of the drain system. As for the thump, check under the unit for anything that shouldnt be under there getting caught up in the mechanics. Let us know :-)
