Hi Guys How do I open the door to a washing machine when it has died mid cycle. I cannot power the machine up without tripping the RCD. So it cannot complete the wash and release the door. Without a hammer or crowbar is there a way to retrieve the washing? Thanks Phil -- ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

Without a hammer or crowbar is there a way to retrieve the washing? Yes, and every washing machine repairman knows it :-) Hopefully the machine isn't full of water or there's a pump sump/filter you can open to drain it. Isolate the machine, take the lid off and there'll be something to pull to override or disengage the door interlock. It probably won't be obvious but try googling for your machine model. In many cases just waiting long enough will do it as whatever power is holding the interlock on should run down eventually. Owain |

Hi Guys How do I open the door to a washing machine when it has died mid cycle. I cannot power the machine up without tripping the RCD. So it cannot complete the wash and release the door. Without a hammer or crowbar is there a way to retrieve the washing? Thanks Phil Remove the drain pipe from where it drain into and tip it into a bowl on the floor. It may take several bowl fulls to empty it completely. Water is only retained in the machine, because drain pipe rises up higher than the highest water level the machine ever achieves. To drain it in normal operation, needs to use a pump in the bottom. Once it is drained, you can usually take to top panel off and gain access to the door latch to manually release the door. Tripping an RCD, is usually due to carbon from the worn motor brushes shorting the motor internals to ground. Worth cleaning out and fitting new brushes, usually. |

And have plenty of towels and or shallow trays around when it does release.
Most seem to release eventually but if you have one that does not then I really do not know unless somebody in the service business might have a particular trick for your make.

laid this down on his screen : In many cases just waiting long enough will do it as whatever power is holding the interlock on should run down eventually. Often an electrically heated wax unit. The wax expands, and blocks the door release for several minutes until the wax cools and contracts. Sometimes the door release mechanism is solenoid, so power is needed to release it, but that will not operate with water in the machine. So drain it first, then remove the top cover with the machine unplugged and look down for a mechanical release. Harry is correct. You need to get the water out first. Sometimes you can just lay the outlet hose low, almost along the floor, and drain the water something. Ive never had a machine this didnt work for but Ive heard some have valves. If yours does, tip it up and undo the drain from the drum, with something under it. Make sure the machine is unplugged. The door interlock should release when cool and the water is out. A common reason machines dont drain is a block in the level sensor pipe. The level sensor is generally round or a rounded rectangular box maybe 3 dia or long, above the middle of the machine. It has a few wires and a small pipe which connects to the lower part of the machine. Check the pipe isnt blocked, a common place is where it connects to the lower end. Problems spinning is a common symptom of a block in this pipe as the machine wont spin if it thinks it has water in it. Sometime, a partial block will just cause things to be delayed until the air in the pipe escapes past the blockage. |

Not sure about the bubbling, the pipe is normally connected at the top of the sump area which should be empty when you are working on the machine. Generally I find the blockage is a grey gunge, a mix of chalk, washing powder (or fluid), oil from the wash, and dirt. The same gunge is often in the other parts of the machine. |

Do you happen to know of a good summary of neutral-earth shorts? I've done a bit of searching and am even more confused! For example "... I would look for a neutral/earth fault. Not only can these can cause an RCD to operate, but it is also possible for a neutral/earth fault to defeat an RCD and prevent it from operating." (at https://community.screwfix.com/threads/rcd-not-working-then-ring-main-neutrals-connected.187153/#post-1501878) Others have responded to the question of double/single pole MCB. What has to be understood is that RCD's are triggered to open on a fault, by an imbalance between current of live versus the neutral conductor. Most MCB's are single pole, isolating just the live. If there is a voltage differential between the N & E (there is usually several volts difference), even if the MCB is open, with a N&E leakage, or short/ or fault - current can still flow down that neutral, through the RCD and cause it to trip. Which is why so many people have such difficulty finding the causes of an RCD constantly tripping. Simply turning MCB's off or unplugging alone, may not allow an RCD to be reset. |
Washing Machine Woes
Brian Reay used his keyboard to write :
Agreed We replaced one with a Siemens which, when it failed (out of warranty) I discovered used some identical parts inside to the Bosch it had replaced- to the point some parts Id kept from the Bosch would fit and allowed me to repair it. Lots of the smaller parts in CH boilers, washing machines, cars and many other things are common to many other makes. Why make something from scratch, when you can buy off the shelf and add a few extra percent, by putting it one of your own boxes? |
