Bosch SHV430 Dishwasher low water pressure to jets

A friend has a dishwasher that they want me to look at for a water pressure problem. They say that the motor or pump is making a strange noise and that the dishes aren't fully wetting. About a month ago they had an expensive whole house water filtration system installed. I am thinking that when the whole house filter was installed some contaminants became loose and were deposited in the supply screen to the dishwasher. I expect that the machine will have to be pulled to get to the hoses to clean or replace the screen(s). If so how is this done?

Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.

SOURCE: Loud humming noise when dishwasher is filling up with water

your model is pretty new. just so you know your warrenty is 1 year parts and labor. 2 years on parts. it should not cost that much money.

there are two components that start before the circulation pump.(wash noise you hear)

first sounds you hear will be the drain pump. usually rattling noises if something is in it but it can make a hum noise if something is jamming the drain propeller up. which is accessible with a T20 torx driver. take the filters out and the mesh filter. and unscrew the screw in the base towards the left. pull out whatever is lodged.

the other humming sound can come from the next component that activates is the watervalve. make sure you dont have a kinked water intake line. otherwise its a bad valve. i have had to change a few of those water valves out already but not for a hum noise on your model. you have a new style water valve. when brands make new parts we get problems fast sometimes..

FDB1050remo Making a squeaking sound almost as if a belt slipping. Not overloaded and nothing rubbing on washer blades. My only guess is that it may be related to low water pressure. Is that possible?


please make this test and fix it. God bless you


Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.


Enter your model number to see parts for your dishwasher.
Help me find my model number


Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.

Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.

Help me find my model number


Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.


Enter your model number to see parts for your dishwasher.
Help me find my model number


Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.


Enter your model number to see parts for your dishwasher.

Circulation and Drain Pump Motor

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the motor sound, it's likely that the circulation and drain pump motor bearings have failed. Once this happens the motor will have to be replaced, the bearings are not repairable.

Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

Press start and a whining noise happens


at the start the first thing that happens usually is the last water from the previous wash may be removed, so it could be the evacuation pump with little water in it, if this also happens at the end of the wash this would indiate this problem. the next thing is the water is taken onboard, due to model either the noise is from a pump that pumps the water in, or from teh water inlet, pressure which maybe to high or low. or from a aquastop shut off solenoid which has to be open, but usually they make more a buzziing noise when they have a problem. first check would be to ensrue your water pressure is ok then take it from there.

i hope this was useful.

My dishwasher makes a strange noise when I switch it on and doen not take in any water.


It is possible that the machine does not start off the cycle because there are errors or feedback from the inputs. For the program to start up the main program controller must initiate the INLET/PUMP MOTOR/DRAIN to work when it is commanded .If this does not happen then the voltage at these points must be checked or the fault relates to no voltage/drive from the controller. This means the controller is a suspect.

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor. The water pressure must be good and the spraying must be seen to be good. If there is low pumping or pressure then the spray arms will not turn around to inject with pressure. If so the pump must be checked for clogging.

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the drain valve/pump activated so as to drain off all the water.

Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.

Fridgeair dishwasher not working making loud sound. water comes in and I can make it drain out but washer does not start


Hello

bearings in the heater fan may get worn out or rust. If this happens, it may become very noisy, either grinding on the bearings, or scraping against the rust. If this happens you need to replace the fan motor. Sometimes, a fan blade may come loose, and you need to replace it.
Sometimes it's the motor that makes the noise you hear. The motor has bearings in it which may become worn or get rusty. When the bearings get worn, they allow the shaft to wobble which can get quite loud. If there is a spin seal leak, water may get inside the motor, washing the bearing grease away. If the spin seal is leaking, you'll notice water leaking from under the dishwasher. There is also a disc attached to the top of the motor called a slinger. It sometimes breaks off and spins around the motor's shaft while it turns, causing some noises. You will need to replace the motor if the bearings are bad. You also need to replace the motor if the slinger is broken as well.

Newer dishwashers may make a squealing or rattling noise on the first run. This is because it has not had any water in it yet, and the motor seals are dry. You may hear this in a unit that hasn't been run in a week or more as well. You should operate the dishwasher regularly to keep the sump water from getting smelly, and to keep the seals lubricated. You can add a quart of water to the sump before running it.

Rattling noises may be produced by dishes rattling inside the dishwasher due to the water pressure from the sprayer arms on the dishes. To determine if the rattling is a loading issue, run the unit empty. If the sound is persistent, it may be that there is debris in the pump.

dishwasher water-inlet valves are noted to make a hum that lasts about 60-90 seconds several times during a washing cycle. This hum is a different hum than the sound of the motor running.

A rhythmic knocking or thumping sound may be caused the sprayer arms hitting something as they go around and around. Rearrange the dishes and resume the wash.

A clunking or clanking may be heard when the detergent cup opens; while a clicking sound may be produced by the timer or electronic control panel.

A solenoid makes a snap sound when it opens. This happens about six times during each load.

Pipes rattling or banging may be caused by a water hammer effect. Water hammer sounds are caused by a valve closing in the system, and yet the water in the pipe is still flowing because of its kinetic energy. The sound is caused by the water slamming into the closed section of pipe. A plumber can install an anti-hammer device.

Small objects can sometimes get stuck in the pump. When this occurs, you'll need to open the pump and then remove the item that is making the noise or replace the pump. The dishwasher pump is usually mounted directly to the motor and runs off the motor as well. The pump is also attached to the bottom of your dishwasher.

As soon as the motor starts up after the dishwasher fills, the motor makes a loud grinding noise that turns into high pitch whining. Water begins leaking from above the pump.


That shows a leaking water seal. Water would run into the motor bearings which then rust and make noise. You probably need the motor / pump kit.

Bosch dishwasher working for 2 minutes and saying check water and coming up e14


Possible that the inlet flow of water is low and so there is time taken to fill up . So check the pressure at the inlet. Also if the water level pressure sensor is faulty then the program will be halted as the water level is not indicated.
Please check the sensor.
