Question about Whirlpool GU2400XTP Built-in Dishwasher

1 Answer

My unit used to send steam out of the top but no longer gets hot. I'm sure the coil should be replaced. This unit was pricey and is used every 7-10 days over the last 14 or so months. My last unit lasted 15 years. How difficult is it to change the heating coil? How much is the suggested retail price?

Dishwasher not cleaning dishes; water not coming out of top spray arm


You are right to go to the inlet filters. If they are clogged you would lose pressure, but not that much...The pressure pump is probably not outputting any longer. Locate it and see if it is moving freely.

Tip

Ventilate error -


The following procedure works when you get the ventilate error:



The Ventilate sign can be due to one or more of the following reasons:
Cause 1- Water leaking from the inlet valve below the water tank. The hose from the inlet valve to the pump can be air locked. When using the hand pump, do not thrust its nozzle too deep
Cause 2- Blockage in the passage of water due to clogged passage anywhere between the pump and espresso delivery nozzle.
Cause 3- Pump is not working. Open steam/water outlet knob and hear the pump work. If you do not hear any noise from the pump, this may be the main cause.
Cause 4- Flow meter is faulty. This part is like the water meter for homes. It measures the flow of water and signals the electronic board. The malfunctioning flow meter will not send signals even when water is flowing through it.
Cause 5- Hose is disconnected and water is not flowing in the system.
Cause 6- O-rings at hose connection is leaking, reducing the water flow to be sensed by flow meter.
Cause 7- Boiler gasket is leaking. Reduces flow of water through the system.
Cause 9- Brew unit is blocked, blocking flow of water through the flow meter. This also causes pump to slow down and ultimately stop with muffled sound within 15 seconds.
Cause 10- Brew unit not connecting brew valve, preventing flow of water. Same sign under cause 9.
Cause 11- Steam is leaking. Registers reduced flow of water at the flow meter.
Cause 12- Solenoid valve is blocked or solenoid coil is bad. Same observation as cause 9.
Cause 13- Electronic Control board is bad. Though rare it can happen due to condensed water from leaking steam. When steam is leaking or boiler is leaking, machine should not be used any more to prevent steam shorting the Electronic board.
Some of the above causes can be checked and corrected before seeking technical help. Do not assume anything without physically checking each of the following:
1- Make sure the water tank is full. If the water tank has water level float, make sure the float is in its housing and it floats as water is filled in the tank. If the level float does not rise with the level of water, then replace the float.
2- Water is not leaking from below the tank. The inlet valve is good. If leakage is present, replace the gasket in the water inlet valve.
3- Prime the machine by opening the hot water knob for 20 seconds or pressing the hot water button. Hot water flow shows the boiler is not blocked with minerals and pump is good. The solenoid valve is good.
4- Water & steam flowing normal, check the brew group for blockage. Determine when was the last time brew group was cleaned. Clean the brew group as explained elsewhere on these pages. If the machine has pre-ground function, try making a fake espresso (without coffee). Make regular espresso in other models to make sure that water goes through brew group and espresso is dispensed.
4- If hot water does not flow because the pump is not activated, then pump is bad. Replace pump.
5- Pump starts to work but within few seconds its sound is muffled and finally stop. This indicates there is serious blockage in the water line or the boiler is clogged with mineral deposits. If water is leaking and seen on the counter top, the chances are that water is leaking from hose connections(replace O-rings) or the boiler is leaking from seams (replace boiler).
6- Prime the machine by opening steam outlet for 20 seconds. Steam flow shows that steam boiler / steam outlet is not blocked. If the steam does not flow, then steam boiler or steam passage is blocked. Replace steam boiler or steam valve
7- Check the solenoid valves to make sure that they open & close as the coil is energized. Solenoid valve is located between the pump and boiler. The pump is activated simultaneously as the solenoid valve when espresso selection button is pressed. Some models may have a solenoid valve near the steam valve. In these models, the solenoid valve is activated to allow passage for steam/hot water. If the valve is not functioning, the ventilate sign will appear.
7- Hear the pump work when priming the machine. Louder noise from the pump can be due to
** air-locked water hose, or
** water is not sucked from the tank or the pump is sucking air instead of water or
** the diaphragm inside the pump has lost flexibility and not developing pressure to push water forward
** the hydraulic system is blocked at one or more locations due to mineral sediment. Find the location and cause of the block and correct it.
** Clean the brew unit (see cleaning instructions) and make sure that
a- the ground coffee used is not powdery fine.
b- The dose of coffee grounds is not in excess specification
c- check if there is blockage. Find the cause and remove it.
8- If steam and hot water flow is normal, but the ventilate sign persists, then the flow meter or the electronic control board is bad. Replace flow meter or the control board, as necessary.

Try also the following:

  • Press hot water button once. Message on the screen will not change, this is normal.
  • Open the steam knob and allow the water to flow freely from steam wand into a cup. The screen should now read "Hot water,ventilate", you may need yo empty several cups of water before message changes. In some case it is necessary to refill the machine container without interrupting the operation.
  • As soon as the screen displays "hot water," turn the steam valve off .
  • If the machine warms up again, then problem is fixed.

Water shoots out of steam valve and can't make espresso


Samantha,

The steam function and the expresso use the same elements to create the steam but the valves will direct the steam to the expresso unit or the steam arm. Most likely you have a faulty valve. In most cases the valve will not open until the pressure gets to the right level. If you are just getting hot water out of the steam arm instead of steam via the expresso unit it most likely means that the valve is faulty. The valves can be replaced but is not easy. You will need to have the unit serviced or you could try to replace the valves. Make sure the flow meter is working before you replace the valves. You can check the operation of the flow meter by running the hot water cycle and making sure that you get the right amount of hot water. Good luck!

The first problem I believe you have is your hot water entering the unit is NOT hot enough. Turn up the temperature setting on your hot water heater. The water in your pipes should come out around 120 degrees Fahrenheit. That should be hot enough to burn your skin so use a thermometer to test. Second the internal heating coil may be burnt out or operating very low and may need to be replaced. For it to sterilize it needs to heat the inside to over 212 degrees Fahrenheit when steam is created. You should definitely make sure that the unit is drying your dishes and steam is spewing out the front exhaust vent during that cycle. Third the soap you use should be a better quality such as Cascade, or Finish. You may also try 2 TBSP of bleach during the WASH cycle. Which will also cause to sterilize.
The only reason you can be getting mold is lack of heat. If you are saying it is a recent problem then I would consider how old is the machine? And look toward the heating coil element.
If the heating coil is working, the washing unit may not be getting enough power. Make should the circuit is properly load rated so it is getting enough electricity to get it hot, hot, hot.

Radiators only working on the top third? please can anyone help! it is a central heating system


If old cast iron units, they are probably filling with rust and debris not allowing the water or steam to get to the lower sections. You will need to have them cleaned. Not an easy fix. They will need to be removed and either power washed or acid dipped. Make sure the valves are open fully to allow as much flow through them as possible.

Most likely it is the fuse that regulates the heating element on your press that has burned out.
All you have to do is open the top, remove the heating plate. The fuse will be on the left, button shaped.
Replace the fuse and put everything back together and the unit should work.
You can buy a fuse from the company you bought your press at or contact the manufacturer.
