Slow leak under unit cannot find problem. what specific should i look for?

Have you checked the internal hoses and the drum seal?

If you are mechanically inclined and know what vacuum lines and reservoirs look like, then open the hood and take a long very slow look at all of the vacuum lines, paying extra attention to the smaller plastic lines where they connect to larger objects. There may be two, three or more reservoir canisters, plastic or metal to maintain a constant even vacuum for various systems on the van. If you can specifically identify which reservoir is for your heater controls, it will help you locate and repair the leak. Fixing the leak is easy, finding it is the hard part. Last is to look for the leak under the dash panel, while the main control unit and individual flap controllers can go bad, it is rare. Most likely cause is a cracked or broken line under the hood, or even just pulled loose from someone working in the engine.

you might need to replace the bottom section and spare parts should be available readily online. I had a slow leak on my samsung side by side and it was resolved once i bought a new part...Hope this is of some use but not an expert.....

severe oil leaks would be front timing cover crankshaft seal and the rear main seal or leak at oil pump at front timing cover oil leaks can come from damaged oil filter seal or damaged oil pressure sending unit.slow oil leaks oil pan gasket the valve cover gasket leaks you will see and smell smoke from under engine compartment which could be a fire hazard.

Replaced.

The use-and-care manual says that the 'product will eventually fail,' and to install a drain catch pan.
The product has stainless steel tank with 3 year warranty. 1-800-558-5700.
The manual does not show parts diagram, element, or anode rod. This indicates that operation is inside a sealed 1-piece unit not meant for repairs.
High clorine content of water, and hard water, and water pressure over 80 psi will adversely affect any tank heater, and shorten lifespan causing probable leak.

Turn off power:
If you can remove cover from H770, then inspect 750 watt element for possible leaking. Then replace with new element of unknown type if element is leaking.
If leaking is coming from the tank itself, then the unit cannot be repaired. This is true for all tank water heaters.

leaking from the fill valve under the tank or running into the bowl via the overflow tube? please be specific:)

I repair them. There are so many places it could be leaking from, you need to be more specific. To answer your question, yes they can be repaired. Get an estimate first, if you decide to have it repaired. The cost of repairs sometimes is more than buying a new one, or close to it. With a new unit you get warranty coverage too

Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.

If leak continued then you must have a faulty cut off valve. Check and tighten valve. Also, check the hose that runs underneath the fridge for cuts or holes.
