I bought a second hand Samsung fridge freezer and have no idea how to connect to water mains? can't see any conditions anywhere

There is a drain tube located under the panel of most freezers. If that clogs up, the auto defrost can't work. The freezer defrosts by evaporating all the moisture out of the compartment. So, check that first. Secondly, a leaky door seal can also cause that problem. You can order door seals online or on Amazon.

or freezer not cooling, but fridge is and a lot of noise from compressor.
Also, fridge drain hole blocked, water in bottom of fridge.

This is a common fault in Hotpoint Fridge Freezers and can also happen if the door has been left open or has been a power cut.

1. Turn off fridge freezer, or at least turn down the freezer temp to minimum, though not ideal.
2. Open freezer door and remove all drawers.
3. Remove the back panel on the inside of the freezer. This is held in place with 4 screws, which might be 6mm hex head or star allen head. Pull the panel out.
4. Behind where the panel was, there is a cooling element for cooling, pipes, and below this a temperature sensor. If the fridge freezer is not switched off, then fold together a few layers of tinfoil and wrap around the sensor.
5. Use a hairdryer to slowly melt the ice. Melt it around areas where it appears to be hanging on, such as the corners of the cooling element or bolts, as well as any thin sections below the main block of ice around the cooling element, which will be supporting the main block. Use a plastic ice scraper to remove ice but not near pipes or sensor.
Warning: Be careful using electrics around water & melting ice & drips.
6. Below the cooling element, there is a drip channel & drain hole. If this hole is full of ice, pour a small amound of warm water down, leave for 10 seconds and pour a bit more until clear.
In the fridge, clear the drain hole in the same way.
Warning: Do not pour a lot of water down, as this water drains onto a tray above the hot compressor at the rear of the fridge freezer to be evaporated by the heat of the compressor and the tray will only hold a small amount.
7. When all ice is removed, dry all moisture. Put the shelves back. Close door. Turn on fridge freezer. Turn up the freezer temperature to your normal setting. Turn on fast freeze if available. After 1 hour, check with a thermometer. It should be cold enough after 1 or 2 hours.

They generally use 1/4" tubing.

Sounds more like compressor failing to pump than board fault

Is the freezer itself getting cold.To blow cold air.the freezer should get cold/friezed.the cold air blows from freezer to fridge side.first the freezer side gets cold, then when the freezer side gets enough cool to its set cooling temperature, at that time the defrost cycle starts.In defrost cycle the fan in the freezer starts running and the cool air from freezer starts going to fridge side.There is a ventilation passage between fridge and freezer from where this cool air passes.---------------- If in your case, the freezer is getting proper cold, but its not blowing cold air from freezer to fridge, then possibility is that, there is a blockage in ventilations.But if ventilation its clear, then its defrost problem.First try manual defrost reset procedure. The procedure is as follows: ---- First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take near to 4 hours to get run in its proper cooling cycle. Then check, if the problem returns again. Then its defrost board problem. ------------------------- BUT if in your case, the freezer section itself is not getting cold, then the problem is compressor related.The compressor is the part which cools the freezer frost.In the compressor, there is a refrigerant to cool the freezer.If the compressor gets weak or the refrigerant gets low, then it will not cool the freezer, if the freezer is not cool then it will blow warm air from freezer to fridge, in defrost cycle.In that case, the compressor is faulty and its the cause of problem.------------ So you will have to first check , that is your freezer getting cold or not.as per that you can start the troubleshooting.------------------

You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

I think you are referring to the water filter alarm. When it first starts coming in, you only notice it when you blink. As time passes, the color becomes more pronounced....If this is right, we'll move on from here, if not, please re-post, and please don't mention the village idiot (me).
The alarm can come on if a high differential pressure is sensed across the filter, or it can come on at pre-programmed times. If the fridge is relatively new, and the quality of the water is good, you can reset the alarm. On my model, I hold down the "ice type" and "child lock" buttons for about 5 seconds. The actual filter is located in the fridge, on the upper right hand side. These filters are somewhat expensive. I say that to say this....You can extend the life of your filter by installing an in-line filter between the wall water valve and the back of the fridge. This will act as a pre-filter for the Samsung filter. They cost usually about a quarter of the cost of the Samsung filters, and are easily replaced. Should you decide to replace your filter, Ebay is a very good source at a less than retail price.
Hope this was what you needed...regards --W/D-- Please feel free to rate this solution!

Hi I have the same problem,
did you get an answer to your question..?

If you mean icemaker or water supply it's easy you just have to connect a water pipe 1/4 to your main water supply of your sink 1/2 inch. Just putting a valve first on the 1/2 pipe reducing to 1/4 & you bring it to your water valve solenoid of the fridge. That's it!
