Whether you’re putting in all new appliances or simply replacing a worn-out machine, installing a dishwasher yourself is a DIY project that’s not that difficult and can save you a hefty installation fee. The first step is making sure the machine will fit in the opening. Most standard dishwashers require a 24” opening. If you’re installing new cabinets, it’s important to consider the width of the dishwasher ahead of time. The height of most machines is adjustable within certain limits, but check to be sure the dishwasher you plan on purchasing will fit your opening before buying. Depending on your cabinet configuration, you may need to drill one or more holes to run supply lines, electrical wiring, and the drainpipe through. Hole saws make quick work of drilling larger diameter holes. Remove the faceplate at the base of the machine to access the supply line inlet and electrical box. It’s a good idea to connect the wiring, drain, and supply lines before pushing the dishwasher into the cabinet, since it makes it easier to access the underside of the machine.

Start by connecting the drainpipe to the discharge pump.

Ikea Ektorp 3 Seater Sofa Bed CoverMount the air gap in one of the sink holes or drill a hole for it in the countertop. Harrisburg Hotels With Hot TubsConnect the drainpipes to the air gap and secure them with hose or spring clamps. If an air gap is not required, loop the drain hose up near the top of the base cabinet, and attach it to the wall with a strap to prevent backflow from the sink. Run the drainpipe to the inlet of the garbage disposal and secure it with a clamp. Many garbage disposals have a plug in the inlet, so be sure to remove it first.

If there isn’t a garbage disposal or an existing drain for the dishwasher, replace the drainpipe under the sink with a dishwasher branch tailpiece and install it above the trap under the sink. Most dishwasher supply lines are 3/8” diameter, but check to make sure you’ve got the right parts before starting the job. Begin by turning off the water and installing a dual outlet shut-off valve to connect the dishwasher supply line to the hot water pipe under the sink. One outlet on the valve provides hot water for the sink faucet while the other attaches to the dishwasher supply line. This will allow you to turn the water off to the dishwasher separately from the faucet. Connect one end of the supply line to the shut-off valve and the other end to the water inlet on the underside of the dishwasher using a right angle elbow. Where needed, apply Teflon tape to the male threads to prevent leaks. Supply lines should be hand tightened then given a solid quarter turn with a wrench.

Always be sure to cut off the power to the dishwasher by flipping the circuit breaker before attempting to connect the electrical supply. Run the cable through the back of the electrical box on the dishwasher, and connect the hot (usually black) and neutral (white) wires to the corresponding wires in the box using wire nuts. Be sure to connect the ground wire to the green screw and replace the cover on the box. Turn the water back on and check for leaks, then turn on the power and run the dishwasher through a full cycle. If everything works properly, slide the machine into the cabinet, being careful not to crimp or pinch the pipes. Plumb and level it by raising and lowering the adjustable feet on either side. Screw the dishwasher to the underside of the countertop to hold it in place. When attaching the mounting screws to the plywood used to support a stone countertop, be sure the screws do not protrude into the stone. Attach the faceplate to the base, and your new dishwasher is ready to go!

In this article, Chief Engineer Geoff Cronshaw looks at some of the key requirements and frequently asked questions. The particular requirements of this section apply to the electrical installations in locations containing a fixed bath (bath tub, birthing pool) or shower, and to the surrounding zones as described in the Wiring Regulations. The Wiring Regulations do not apply to emergency facilities, for example emergency showers used in industrial areas or laboratories.The 17th Edition, published in 2008, introduced a number of amendments. These included changes to the zonal system, RCD protection on all bathroom circuits, and 230 V socket outlets permitted 3 m horizontally from the boundary of zone 1; supplementary equipotential bonding may be omitted subject to the Wiring Regulations being met.Horizontal or inclined ceilings, walls with or without windows, doors, floors and fixed partitions may be taken into account where these effectively limit the extent of locations containing a bath or shower as well as their zones.

Zones 0, 1 and 2 provide a very practical method of specifying requirements (for example, for the protection of equipment against the ingress of water and protection against electric shock, etc) in a specific and unambiguous way. Equipment is either in a zone or outside a zone and this can be easily determined by measurement.The height of zone 1 and zone 2 are limited either by the horizontal plane corresponding to the highest fixed shower head or water outlet, or the horizontal plane lying 2.25 m above the finished floor level, whichever is higher. Regulation 701.411.3.3 requires that additional protection shall be provided for all circuits of the location by the use of one or more RCDs having the characteristics specified in Regulation 415.1.1. This was a significant change introduced by the 17th Edition. This means that all circuits, including lighting, electric showers, heated towel rails, etc. require RCD protection not exceeding 30 mA.The 17th Edition introduced another important change: Regulation 701.512.3 permits 230 V socket outlets to be installed in a room containing a bath or shower, providing they are installed 3m horizontally from the boundary of zone 1.The 17th Edition introduced a significant change for supplementary equipotential bonding.

Regulation 701.415.2 states that, where the location containing a bath or shower is in a building with a protective equipotential bonding system in accordance with Regulation 411.3.1.2, supplementary equipotential bonding may be omitted where all of the following conditions are met:(i) all final circuits of the location comply with the requirements for automatic disconnection in accordance with 411.3.2;(ii) all final circuits of the location have additional protection by means of an RCD in accordance with 701.411.3.3; and(iii) all extraneous-conductive-parts of the location are effectively connected to the protective equipotential bonding in accordance with 411.3.1.2.This means that the designer needs to make an assessment that all extraneous-conductive-parts of the location are effectively connected to the protective equipotential bonding, in accordance with 411.3.1.2.Any wiring system or equipment selected and installed must be suitable for its location and able to operate satisfactorily without deterioration during its working life.

The presence of water can occur in several ways (for example, splashing, steam/humidity, condensation) and at each location where it is expected to be present its effects must be considered and suitable protection must be provided.Consequently, Section 701 requires that electrical equipment in zones 1 and 2 shall have a degree of protection of at least IPX4.Electrical equipment exposed to water jets (for example, for cleaning purposes), shall have a degree of protection of at least IPX5. Section 701 does not specify any additional ingress protection requirements beyond zone 2. This means that accessories, such as switches and fused connection units, can be installed beyond zone 2, subject to the requirements of Regulation 512.2 (external influences).Regulation 701.55 restricts the type of fixed and permanently connected current-using equipment that can be installed in zone 1. Washing machines and tumble dryers may be installed in a bathroom provided they are:The minimum degree of protection for equipment installed in zones 1 and 2 is IPX4, or IPX5 where water jets are likely to be used for cleaning purposes.

An exception to this requirement is a shaver supply unit complying with BS EN 61558-2-5 which, although it does not meet the requirements of IP4X, is permitted in zone 2 but must be located where direct spray from showers is unlikely. This type of shaver supply unit is the only type that is permitted in a bathroom or shower room.Are 230 V extractor fans permitted in zones 1 and 2 of a room containing a bath or shower?Yes, a suitable 230 V extractor fan may be installed both in zones 1 and 2, and outside the zones. If an extractor fan is installed in zone 1 or 2 it must be protected against the ingress of moisture to at least IPX4 and be suitable according to manufacturer’s instructions. Regulation 701.512.2 requires that equipment exposed to water jets (for example, for cleaning purposes), shall have a degree of protection of at least IPX5.An extractor fan supplied from a lighting circuit for a bathroom without a window should have its own means of isolation, as otherwise replacement or maintenance of the fan would have to be carried out in the dark.

An isolation switch for a fan with an overrun facility will need to be triple-pole (switch wire, line and neutral), and must be installed outside zones 0, 1 and 2.Are 230 V socket outlets permitted in a room containing a bath or shower?Yes, 230 V 13 A socket outlets are allowed, but only if they are at least 3 m horizontally from the boundary of zone 1.Are 230 V lighting switches (plate switches) permitted in a room containing a bath or shower?Yes, a plate switch is allowed outside the zones of a bathroom. A switch should be at least 0.6 m from the edge of the bath or shower (outside the zones) and must be suitable for the location. The cords of cord-operated switches are allowed in zones 1 and 2 and are recommended for bathrooms and shower rooms to account for the humidity and condensation that could occur.Are 230 V light fittings permitted above a shower or bath (zone 1) in a room containing a bath or shower?Yes, 230 V fittings may be installed above a shower or bath but they must be at least IPX4, i.e. enclosed and water protected.
