At first remove the Battery before you open the Laptop. Have some any tools like screw and smoothly remove all pins and put it in one place. Also remove any plug in play device like CD/DVD Drive which is very easy to pull out.

Clothes washer fills but then stops and won't agitate or go into spin cycle!

Chances are the lid/door switch is malfunctioning. But in many cases it is the plunger that attacks the switch that has failed. Before replacing the switch, try activating the switch manually. Caution: Use a non conductive plastic item when trying to activate the switch manually. You are dealing with water and electricity at the same time. Precaution is required. Most replacement parts of this nature are between $16 - $50 and a service call requires removal of the lid and front door assemblies and in some cases more part removal. Average repair time 30 - 45 min.

Water starts to spray from the bottom of my Bosch Aquatak 120i when i turn the water on. Is it still safe to use when this is happening

Electricity and water can be a hazard which could be life threatening, but you can operate electrical equipment in a wet environment if you are careful and follow safety precautions. Most import, make sure the electrical outlet you are using for the pressure washer has a working ground plug. Just because an outlet has three prongs does not mean the ground is working. You need to use an outlet tester which is inexpensive from a hardware store or use a multi meter to test the ground for conductivity to earth ground. Your power washer should have a working GFI (Ground fault interrupter), and you need to press the test button to make sure it is working. If your power washer does not have a GFI purchase one from a hardware store. I would also plug the power washer directly into the electrical outlet since an extension cord could have a bad ground connection and will cause the power washer to pull more current from the outlet. Make sure the power washer is raised of the ground so it will not sit in a pool of water. If you follow the safety precautions you should be safe but keep in mind water does not carry the electrical current, it is the impurities in the water which carry the current. Therefore, water could be more conductive depending on the impurity of water. However, it sounds like a loose connection in the power washer which could also be an o-ring or a washer is broken and it would b a good idea to have it fixed.

Safety Inquiry

Improper use of a power inverter could result in personal injury. The inverter should not be installed in the vehicle’s engine compartment. Keep the inverter free from moisture as liquids conduct electricity, which may lead to serious damage or injury! Do not use the inverter near flammable materials or where fumes or gases may accumulate. The AC Output (neutral) wire should be vonded to ground, except in special applications. See owner’s manual for more details.
