01Dishwasher installs
A new unit, a leak after installation and a drain problem each point to a different connection.
Supply, drain and often the disposal connection all come together at one dishwasher. Getting each one right the first time is what keeps a new unit from leaking into the cabinet below.
Usually a supply line, drain hose or air gap that was not sealed or seated properly during installation. It is worth resolving before the cabinet floor absorbs it.
Often a kink in the drain hose, a clogged air gap, or a connection made at the wrong point on the disposal or drain line. The cause is usually in the hookup rather than the dishwasher itself.
02Replacing or adding
The connections already at the cabinet decide how much of the job is new.
The supply, drain and outlet are already in place, so the work is mostly disconnecting the old unit and connecting the new one to the same lines, checked for wear along the way.
A cabinet with no dishwasher before needs a supply line, a drain connection and often an outlet run to it, which adds more work than swapping an existing unit but is routine in a kitchen with access nearby.

03Where leaks start
Most leaks that show up soon after a dishwasher is installed trace back to one of three points: a supply fitting that was not tightened enough or over-tightened and cracked its washer, a drain hose that was not seated fully onto its fitting, or an air gap or high loop that was left out or connected wrong. None of them are faults in the dishwasher itself, which is why the same unit installed a second time, correctly, runs dry from the start.
04What changes the job
No two cabinets are set up the same. These decide how much the connections add to the job.
A dishwasher draining through an existing disposal is usually a straightforward fitting connection. Without one, the drain hose needs its own dedicated connection into the sink drain line instead.
An air gap sits visibly on the counter or sink deck and needs a hole to mount through. A high loop needs no hole but depends on enough slack and height in the drain hose to route it properly.
A dishwasher already near a suitable outlet connects quickly. One far from power, or on a circuit that needs to be dedicated to it, adds electrical work to the job.
05Questions
It stops drain water from siphoning back into the dishwasher if the kitchen drain backs up. Some installations use a high loop in the drain hose instead, depending on the setup under the sink.
Where a disposal is present, the dishwasher's drain hose usually connects to a fitting on it, and a knockout plug inside that fitting is removed first. Where there is no disposal, the hose connects to a dedicated drain fitting instead.
Usually, yes, provided a supply line, drain and outlet can reach the cabinet. Running new lines to a cabinet that never had a dishwasher is a bigger job than swapping an existing one, but it is routine work.
Where the problem is, when it started, what changed, whether the water is off, and the age of the fixture or heater involved. A photo of the problem and of any visible model label helps too.
