Leaking water from the hose connections - Haier HLP23E Top Load Washer

most likely if leaking at the connection is the hose tight on connector. It is leaking where you can see it make sure and when you look at it the leak is it before or after the hose connection?

Sounds like either the hose has a hole in it, it isn't seated right, or it isn't tightened sufficiently at the connection. Most often, leaks by the connection are actually leaks at the connection and the water is running down the pipe a bit. Try turning the water off in the main system or at any valve before the connection and then tightening the connection another quarter turn. While directions caution us to be careful not to tighten too tightly, we must insure that our connections are sufficiently tight so that the water doesn't leak out. You may also take the connection off and make sure you have a layer of plumber's silicon tape on the threads and then put the connection back together, making sure it is tight enough so that there are no leaks. Less likely, but possibly, the hose may have a small hole in it. In this case, the water is likely spurting out of the hole rather than slowly leaking down the pipe.

Well there are only 3 things that could have gone wrong.

1. Radiator Leak - this means the radiator has developed a hole with via corrosion of the metal parts of simply integrity failure of the plastic parts of the radiator.
2. Hose leak - this could be a hole in 1 of 2 hoses that connects the engine to the radiator. Or it can also be a leak where the hose connects to the radiator (clamp Failure).
3. Water Pump breakdown - this is where the gasket in the water pump has failed and is leaking out the water rather than pumping it.

All the problems above has different ways of diagnosing. but we can probably narrow it down.

1. if the leak is near the radiator then it could be a hose connection, hose breakage or Radiator hole.

2. if the leak is nearer the engine then check the other end of the hose and if its not there then it could only be the water pump is leaking. You can check this if there are water stains on the water pump. The water pump on a 1990 corolla is mechanical turned also by a fan belt. Look for a pulley that has a hose connected to the radiator and that would be the water pump.

Troubleshooting Leaks
If the dishwasher leaks, and you know the problem is not related to tub overfilling, the pump, or inlet valve problems, the plumbing connections may be faulty. Most dishwashers are connected to the water supply with metal pipe fittings, and the leak could be at these fittings. If the fittings are threaded, tighten them with an adjustable wrench. If this doesn't work, chances are the threads are stripped or the fitting is cracked or otherwise damaged. In this case, replace the fitting.
Most dishwashers discharge used water through a pipe or a hose connected to the drain or garbage disposer under the kitchen sink. If the drain line is made of flexible hosing, it may have cracked from prolonged exposure to hot water. Examine the hose; if it's damaged, replace it. If the hose is leaking at its connections with the disposer or dishwasher, tighten the fittings or clamps at the connections, or replace the clamps. Also check for water leaks around inlet valves, drain valves, and anywhere you see flexible hoses and hose connections. Leaks at clamps can be stopped by tightening or replacing the clamps. Leaks in hoses can be eliminated by replacing the hoses.
I HOPE THAT YOU FIND THIS INFORMATION VERY HELPFUL

I'm pretty sure the "air hose" is the drain hose from the dishwasher and is supposed to empty in the garbage disposal. Garbage disposals are made for this optional hook up with a plug you have to knock out and remove from the inside of the disposal. If you run the dishwater with the hose not connected to disposal it has to be going somewhere!

Troubleshooting Water Leaks

Water leaks in a washer are often difficult to trace. There are many possibilities to look for. The problem could be a loose connection, a broken hose, a cracked component, or a defective seal. It could also be a hole in the tub. If a hole in the tub is the problem, it's usually best to replace the washer.

Most leaks can be eliminated by tightening water connections and replacing deteriorated components. To stop a leak:

Step 1: Check the lid seal. If faulty, replace with a new gasket.

Step 2: Check the hoses at faucet connections. Tighten connections or replace hoses.

Step 3: Check the hoses at water valve connections. Tighten connections or replace hoses.

Step 4: Check the drain hoses. Tighten connections or replace hoses.

Step 5: Check the inlet nozzles. Tighten connections or replace nozzles.

Step 6: Check the splash guard. Tighten connections or replace.

Step 7: Check any plastic valve. Tighten connections or replace.

Step 8: Check the outlet hose to drain. Tighten connections or replace hose.

Step 9: Check the water pump, using the procedures that follow.

hi Most dishwashers discharge used water through a pipe or a hose connected to the drain or garbage disposer under the kitchen sink. If the drain line is made of flexible hosing, it may have cracked from prolonged exposure to hot water. Examine the hose; if it's damaged, replace it. If the hose is leaking at its connections with the disposer or dishwasher, tighten the fittings or clamps at the connections, or replace the clamps. Also check for water leaks around inlet valves, drain valves, and anywhere you see flexible hoses and hose connections. Leaks at clamps can be stopped by tightening or replacing the clamps. Leaks in hoses can be eliminated by replacing the hoses.
