Model wma58 as soon as the machine finishes it wash cyle and is to empty water gushes from them soap dispenser area .Is there a blockage causing this fault.

The first thing to do is take note of what the washer is doing when water leaks out in order to help pinpoint the cause. Does it only leak when filling? Is it leaking during wash or rinses? Or is it leaking only when it goes into spin?

Only leaks when filling

• Water pressure that's too strong. Some dispensers can't cope with high water pressure. Make sure the washer is level as one leaning forward can leak if combined with high water pressure. Try turning the tap on the washer down. Only suspect this if you know the water pressure is high and it looks like it's gushing in quite fast on fill
• If there is an optional detergent flap fitted in the drawer for holding liquid detergent make sure it is removed or drawn into the up position if using powder otherwise it prevents detergent running down into the drum
• A build up of grease and slime in the nozzles at the top of the dispenser where the water flows in causing water to spray at the front and run out when filling. Check this article -black jelly-like substance in soap dispenser and on soap drawer (In extreme cases I've had to replace the dispenser.)
• A build up of undissolved detergent in the base of the soap dispenser under the drawer (depending on the design). Remove the soap drawer and check the bottom of the soap dispenser for a build up of detergent that could allow water to run over the lip of the dispenser
• Blocked dispenser hose: Some washing machines can flood water out of the soap dispenser if the hose leading out of the dispenser into the tub gets blocked. Blockages can be something put into the drawer by a child or a chunk of undissolved detergent tablet. Indesit, and Candy, as well as some of the later Hoover washing machines suffered from this design flaw. The hose where the water is flushed down, was right at the front of the soap dispenser on these washing machines and it wasn't wide enough. Undissolved powder from a tablet or lumps of detergent through poor water pressure can block this hose solid causing water to back up. Unplug machine, remove lid and feel this hose carefully for obstructions.
• Overfilling: If the washer starts to fill and never stops it will flood out of the drawer eventually - Washing machine overfills

Leaks out of drawer during the wash or rinse cycle

• Too many suds? If you can see the door glass is white with foam up to the top it could be foaming out of the dispenser. Too much foam in the washing machine
• Overfilling: If the washer starts washing but the water doesn't stop coming in it will eventually fill the drum so much it will start to pour out of the soap drawer and other places. If this is the fault you should be able to see the drum is so full of water it's making a different sound, maybe labouring under the load, and the door glass full to the top with water. You should also hear that water is still running into the machine and be able to detect it by opening the drawer. However, in most cases an over filling washing machine should trigger an error code long before it gets to this stage but if you suspect overfilling check this page - Washing machine overfills
• Surging: There are (often intermittent) faults that can cause the motor to spin out of control on wash or rinses. Instead of turning slowly the fault causes the motor to surge into spin instead which throws the laundry and all the water about violently. Water can then be forced out of the soap dispenser drawer. This fault should be relatively rare these days but if you observe this behaviour call an engineer to diagnose the cause.

Leaks from drawer only when spinning

• If it only comes out on spin it can be caused by a partial blockage preventing the water being pumped out fast enough resulting in excess water being thrown around on spin and backing up into the dispenser. This fault is similar to the surging fault described in the last list but different in that the problem only occurs when it's on a proper spin cycle and much of the water has been pumped away. Troubleshooting this fault is all about finding out why it isn't emptying the water properly which is usually due to a partial blockage. Follow the same troubleshooting as described for a washer not pumping any water out at all - Washing machine won't empty water
• If water is being forced out of the drawer when the washer is spinning but it is on wash or rinse and shouldn't be spinning follow the procedure for surging in the previous section above

pull out soap dish and clean out should do it

Some washing machines, can flood water out of the soap dispenser when a hose gets blocked (usually with un dissolved soap powder) .Water flooding out of the front of a washing machine's soap dispenser can also be an indication of overfilling or a partial pump blockage if it does it when spinning.
Black gunge in the top of the soap dispenser can cause water to spray towards the front and leak. Take out the soap dispenser drawer and look at the roof of the soap dispenser. If it's covered in black gunge, blocking some of the water holes, it could be causing problems. In extreme cases you have to replace the dispenser.

What type of detergent are you using?

use liquid instead of powder and always use HE detergent

You need to replace the cold water inlet valve. If the machine is older than one year it may be clogged on the side that moderates the cold water to the bleach and softener compartment. Replacing the valve fixed the problem. During the cycle when the softener dispenser fills it should fill quickly and no or little water should be seen in the soap dispenser area. If a lot of water goes into the soap dispense and little into the softener area the valve is clogged.

it wont be the machinei think.
try doing a hot wash cyle on an empty machine with some descaler powder or soda crystals to clean it out.

you have a blocked filter, unplug from mains, take off back panel you will see a black sump hose coming from the tub to the pump, tilt the machine forward and put a dish or bowl under sump unscrew clamp and pull off slowly to release any water in the drum. You will find a blockage, also what appears to be a ping pong ball dont throw away it is meant to be there.

In the sump hose there is a filter, remove the hose and clean out filter insert, water is being forced up dispenser hose because it cannot empty fast enough.
