I have a 351HT dishwasher and the soap is not circulating into the machine, also sometimes it leaks when it is not working.

Probably because the shorter setting uses hotter water. I expect a hose is leaking when hot.

If it looks like the water is circulating then it's possible that soap build up can cause cleaning problems. Try taking a cereal bowl and filling it with an 8 oz bottle of apple cider vinegar (you want apple cider for the citric acid and you want to put in a bowl because the 1st thing a dishwasher does is drain) then put the bowl on the lower rack and wash nothing but the bowl of vinegar. We have found that the new non phosphate soap is also causing problems we have found that Finish tablets work very well and since they are pre-packaged then there is no risk of too much soap causing problems. If that doesn't help then it's possible that the motor is not turning the spray arm at a high enough speed to circulate the water. Hope this helps.

I have this same dishwasher, bought it May 31, 2011 and the water won't spray. I called Samsung, and they oh so nicely said they would send a tech to take a look at it. I asked for free....lady says yes. Tech gets here and say it's a $69.00 fee just to run the onboard diagnosis.

According to manufacturers, the DW may leak for three reasons:

1. Door not closed properly. Be sure the door closes and the door gasket is not damaged. Inspect the gasket closely, sometimes silverware damages it.

2. Use the appropriate Dishwasher soap. Don't use regular soap. If the dwsoap is too old, replace it.

3. Water sensor not working and the dw is overfilling. Be sure the float switch is working properly and nothing obstructs it.

Hi,

the solenoide which pops open the soap lid may be faulty.

Better to poar your dishwashing powder or tablet in the bottom of the dishwasher tray until you get the machine repaired. You may want to do a prewash rinse first, then stop the machine and add your soap.

Make sure not to use too much soap. Just the normal amount as you would use in the soap dispenser.

you could be usiong way to mauch soap try filling only one of the soap trays or even try doing one wash without any soap at all
this unit tends to do this if you have to much soap in the unit left over from the last load...
beyond that your machine is proibaly tilted to far forward you can lift it, by lowering the front legs begind the toekick

That's a normal path for the soap. It sounds like the water just sits in the bottom without being pumped through the spray arms. Does the pump motor run? Pop the door open in the middle of the washing cycle--you should see hot water dripping from everything and the soap picked up and circulated with the water. If this machine has seen a lot of use, the intake screen under the lower spray arm may be plugged and is accessed by removing the spray arm and working your way down to the bottom of the deck. Might be a problem for a service technician to take care of.

check in side when leaking is there foalm bubbles inside could be getting liquid soap in it if prewashing dishes and not rinseing good kill foalm with large amount of table salt

door lock is in the wrong position. open door and use 2 small screwdrivers to lever lock to correct position. bend the hook on the cabinet slightly downwards if it is a metal hook
rinse aid and detergent dispensors are 1 item. could well be faulty but can also be module. check you are getting volts to the solenoid at appropiate part of the cycle
