How to connect a dishwasher with your own hands: instructions + video

To con­nect the dish­wash­er, you need a cou­ple of hours if you have every­thing you need. If you do not know how to con­nect a dish­wash­er with your own hands, then detailed instruc­tions, a list of mate­ri­als and tools are in front of you.

Dishwasher Connection Tools

You will need:

1. Sew­er siphon for drain con­nec­tion.
2. Shut-off ball valve that will shut off the water in front of the dish­wash­er.
3. ¾” thread­ed brass tee fit­ting for water con­nec­tion.
4. The fil­ter for rough clean­ing of the giv­en water.
5. PVC pipe or high pres­sure hose for drain (if there is no siphon includ­ed).
6. Pli­ers, screw­driv­er, tape, water­proof­ing tape FUM.

It is rec­om­mend­ed to install a tee not steel or cast iron (they rust quick­ly), but bronze or brass, a ball valve — met­al-plas­tic or from the same brass or bronze. So you will ensure long-term main­te­nance-free oper­a­tion of com­po­nents.

Dirty water is dis­charged through the siphon into the sew­er, so it is bet­ter that it be uni­ver­sal — with sev­er­al fit­tings so that it can be con­nect­ed to the drain holes of oth­er house­hold appli­ances.

The siphon also traps unpleas­ant odors from the sew­er, so don’t skimp on it — no mat­ter how much the kit costs, it’s impor­tant that it works for a long time. Be sure to check the com­plete set of the siphon so as not to go once again for the miss­ing gas­ket. The fil­ter for water purifi­ca­tion is used the same as in the water meter sys­tem.

The procedure for connecting the dishwasher

Dish­wash­ing machines are desk­top, built-in (com­pact) and sta­tion­ary. Despite the dif­fer­ence in dimen­sions, the con­nec­tion of all com­mu­ni­ca­tions is car­ried out accord­ing to the gen­er­al prin­ci­ple with minor dif­fer­ences.

How to con­nect a dish­wash­er of any type — sta­tion­ary, com­pact or built-in:

1. Decide on the place where the dish­wash­er will be installed. Most often this is a work­ing area next to the kitchen sink.
2. Choose where you will con­nect the unit to the mains. It is safer if a sep­a­rate ground­ed sock­et is installed, but this applies main­ly to pow­er­ful devices.
3. When installing a sep­a­rate out­let, choose a wire with a cross sec­tion of 2.5 mm² and pro­tec­tion in the form of a 16 A auto­mat­ic machine. The opti­mal­ly reli­able option is to add a 30 mA RCD (resid­ual cur­rent device).
4. Choose a place to con­nect to cold water. But you may have a mod­el with hot water con­nec­tion, so you will need to con­nect the dish­wash­er to hot water.
5. Water is con­nect­ed with a spe­cial high pres­sure hose with a ¾ inch union nut. There­fore, a shut-off valve with a ¾ inch thread must be screwed into the tee.
6. The dish­wash­er drain is con­nect­ed to the inter­nal sew­er­age, and it is bet­ter to orga­nize the con­nec­tion sep­a­rate­ly through a siphon tee (for exam­ple, on a kitchen sink drain).

Sewerage supply

Now about how to con­nect the drain of the dish­wash­er. Drain­ing is the eas­i­est thing to do. To do this, in each kitchen siphon there is a plug at the bot­tom that needs to be unscrewed, and screw the siphon onto this thread, and the hose for drain­ing dirty water from the dish­wash­er will already be con­nect­ed to it.

The stan­dard drain hose is 1.5 meters long and should be enough. The siphon has a built-in valve to delay back­flow and odors from the sew­er, but one more pro­tec­tive mea­sure can be pro­vid­ed — fix the drain hose so that a small half-ring forms below the siphon. It will be a kind of water valve.

Electrical connection

Not every­one knows how to prop­er­ly con­nect the dish­wash­er to the net­work. The best option is a sep­a­rate sock­et, a sep­a­rate cable, ground­ing and sep­a­rate pro­tec­tion in the form of an RCD and a cir­cuit break­er. But this rule is for pow­er­ful units and work for pro­fes­sion­als. We want to con­nect the device our­selves.

So, we con­nect the dish­wash­er our­selves. For a kitchen in which a com­pact machine, such as a Bosch, will be installed, the option of con­nect­ing to the near­est out­let is suit­able. More­over, the entire elec­tri­cal net­work of the apart­ment is pro­tect­ed by not one, but two machines on the land­ing — one before the meter, and one after it.

For a low-pow­er sink, you can buy a ground­ed sock­et plug and make an exten­sion cord with your own hands. Such a ground­ing con­nec­tion pro­tects against the load on the home net­work, and the fact that all wiring wires are con­cret­ed into the walls pro­tects them from over­heat­ing.

How to bring water

How to con­nect a bosch dish­wash­er or oth­er mod­el to water. The sup­ply of cold water requires a tie-in to the water sup­ply sys­tem, and this is not nec­es­sar­i­ly weld­ing work. Just at the place where the water is con­nect­ed to the cold tap in the kitchen, a tee is mount­ed, from which the hose is con­nect­ed to the dish­wash­er.

Thread­ed con­nec­tions must be sealed with FUM-tape (8–12 turns must be made). For a tight con­nec­tion, hand effort is enough, with­out keys. Instead of FUM tape, you can use linen wind­ing, tow or sealant.

Imme­di­ate­ly screw the ball valve (valve) onto the tee, and con­nect a cold water hose to it. If your dish­wash­er mod­el can be con­nect­ed to hot water, then the essence of the process does not change — the tee cuts into the hot water sup­ply pipe.

Features of connecting a portable machine

The desk­top dish­wash­er is installed on the coun­ter­top, the drain is usu­al­ly orga­nized in the sim­plest way — dirty water is drained direct­ly into the sink. Water is sup­plied to the com­pact dish­wash­er in the same way as in sta­tion­ary mod­els, and the pow­er sup­ply is from a con­ven­tion­al kitchen elec­tri­cal out­let.

Stan­dard dimen­sions of the built-in mod­el: width 450–600 mm, unit depth — 550 mm, height — 820 mm. The built-in mod­el is installed in two ver­sions:

1. In a spe­cial­ly des­ig­nat­ed place in the kitchen (like a wash­ing machine or mini-refrig­er­a­tor) under the coun­ter­top, tak­ing into account the size of the future unit.
2. As a sep­a­rate cab­i­net, dec­o­rat­ed to match the kitchen fur­ni­ture. For this, spe­cial facades for dish­wash­ers are sold, from which you can choose the right decor.

Con­nect the built-in dish­wash­er to water, sew­er­age and volt­age in the same way as in the sta­tion­ary ver­sion. And which mod­el your dish­wash­er will belong to: built-in, portable or sta­tion­ary — it depends only on the size of the kitchen room and your desire.

Features of connecting a stationary machine

You can find out how to con­nect the dish­wash­er your­self from the instruc­tions for the appli­ance. All tech­no­log­i­cal process­es described in the instruc­tions are accom­pa­nied by pic­tures and marked to fol­low the sequence of oper­a­tions. Often, not every­thing is clear from the pic­tures, so use our advice.

The instruc­tion may not con­tain the fea­tures of the process, how to con­nect the dish­wash­er to the sew­er, drain and volt­age exact­ly for your con­di­tions, so you need to pro­ceed from the actu­al dimen­sions of the unit and the loca­tion of com­mu­ni­ca­tions. You may need to length­en the drain hose or buy anoth­er siphon.

Checking the operation of the dishwasher

Before the first run, check:

1. Cor­rect con­nec­tion to the mains. To do this, sim­ply turn on the machine for a few sec­onds.
2. Water sup­ply to the unit and drain. Check all hoses for kinks and all thread­ed con­nec­tions for leaks.
3. Check the degree of incli­na­tion of the drain hose — ide­al­ly, water should not stag­nate in the hose, unless you your­self have orga­nized a spe­cial addi­tion­al water plug to pro­tect against unpleas­ant odors from the sew­er.

Now, if all is well, close up all the tech­no­log­i­cal holes in the walls, if any (may be nec­es­sary when lay­ing a cable, drain hose or water sup­ply) and put things in order in the kitchen.

Tips from the user on how to con­nect the dish­wash­er (video) — watch and remem­ber. All con­nec­tions when con­nect­ing drain and water require only man­u­al effort — spe­cial keys are not need­ed for this. A min­i­mum of tools and phys­i­cal effort — and your dish­wash­er will start work­ing.

Even a house­wife can han­dle con­nect­ing a dish­wash­er, and there is no need to call a spe­cial­ist. Just fol­low the sequence of oper­a­tions, ensure that all mate­ri­als and tools are avail­able, and you will suc­ceed.
