The short answer
Start from a tall item deflecting water at the door: on a Taj dishwasher that is the likeliest explanation for what you are looking at, and a failed pump seal or a cracked sump is the least likely. Most of this you can settle before anyone is called.
What the symptom looks like
- Water on the floor at the front of the door — Escaping past the door seal, or running down the inside of the door and out under it.
- Damage to the cabinet floor with no visible puddle — A slow leak at a hose clip that has been running for months.
- NEAR MISS: condensation at the vent on a hot cycle — Normal. Steam escapes by design on many machines.
Causes ranked for this brand, likeliest first
- A tall item deflecting water at the door — A baking tray in the front row turns the spray straight at the door and beats the seal on pressure alone. First here, for a reason specific to Taj: the cavity is small, so how it is loaded changes the result far more than in a full-size machine.
- The machine out of level in its cut-out — Tilted forward, the water line in the base sits against the door rather than below it, and it leaks on every fill. Second, because a compact unit is carried in and set down, never really installed, and nobody re-checks it once it is loaded.
- A dirty or hardened door seal — The gasket seals on a thin lip. Food residue on it, or rubber that has gone hard, opens a path at the bottom corners. Third: the gasket compound on a value build hardens sooner, so the seal is live well before the machine is old.
- A failed pump seal or a cracked sump — Water arrives under the machine with nothing visibly wrong above it, and it only appears while the pump runs. Last, which is why it is checked last: the pump is the cheapest moving part in a value build, so it is the part that gives up first.
What to check first, second and third
- Look at what was in the front row of the bottom rack — A machine that leaks only on certain loads has already told you the answer.
- Check the machine is level side to side and sits very slightly back — An install fault reads as a seal fault from the front.
- Run a finger right around the seal and look at the bottom corners — Residue and a flattened corner are both visible and both fixable.
Owner checks, in order
- Reload with nothing tall in the front row and run the same cycle — If it stays dry, the machine is fine and the loading was not.
About 15 min
- Level the machine in its cut-out and check the door closes square against the frame — A machine that has been pulled out and pushed back is often left tilted.
Tools: a spirit level, an adjustable spannerAbout 25 min
- Wash the door seal and its channel with hot soapy water and check it sits proud all round — Replacing a seal is often unnecessary once it has been properly cleaned.
Tools: a cloth, hot soapy waterAbout 15 min
- STOP HERE: a pump seal or a cracked sump needs the machine out and stripped — A service call, not an owner check.
Before you open anything
Safety
Switch the machine off at its breaker or unplug it before removing the kick plate or any panel, and shut the supply off at the stop tap. A capacitor can hold a charge after the power is off. Never defeat the door latch to watch a cycle run: it holds hot water and a spray arm behind it. Water and a live terminal in the same cabinet is the one combination worth being careful about.
Where the owner fix ends
Call when the seal is clean, the loading is sensible, the machine is level and it still leaks, or as soon as you find water reaching a socket or the cabinet floor. Isolate the power at the breaker before taking the kick plate off, and shut the supply tap before disturbing any connection.

This page is about the Taj dishwasher as a class rather than one family or model line. Where a family-specific page exists it is linked below and it is the better answer. Not here: seal part numbers, sump diagrams and family-specific torque figures.
